negative · reviewer's own thumbsView post →Kill zombies and collect scrap, then kill more zombies and collect even more scrap. Build some defenses and go wild with killing and... the game ends.
negative · reviewer's own thumbsView post →Neat mix of zombie survival and tower defense. It's fun, short, and an easy perfect.
positive · reviewer's own thumbsView post →The game is really fun to play. The artwork and how you evolve is very enjoyable. But the game is very broken for recent computers. Doesn't matter your GPU, it doesn't make use of it. I have a i7-9700k, 3.6 GHz and the game is unplayable. Game become VERY VERY laggy as you play to a state that becomes unplayable. There are also some bugs to get all achievements as well. I will still try to play more and to have all achievements but I don't recommend buying it even on sale. Really bad optimized…

positive · reviewer's own thumbsView post →IDK how devs do it, but I felt those three MC very charming. Literally Deadly 30 stands for survive 30 days during a war and Zombie apocalypse that happened simultaniously, where upon which an American Soldier found a cottage as refuge, and then found a russian and german Soldier. The three have to forget their differences at war to survive the plague. In 30 days the rescue will come, and nobody cares if they are enemy or allie anymore, only survivors. Fair difficulty, with a lot of lag (but…
positive · reviewer's own thumbsView post →The concept is fun, however, the issues overshadow the positives greatly. You obtain scrap metal during the day to buy upgrades for your base, gear, ammo, and health to survive zombie waves at night. IMO there simply isn't enough day light time to obtain the resources necessary to survive at night. You rely on RNG to spawn broken down tanks and vehicles which provide large sums of metal. The spawn rate of these objects is wayyyyyyyyy to low. The majority of your metal ends up going towards a…
negative · reviewer's own thumbsView post →The game is fun but it is borderline unplayable on modern hardware, experiencing constant lag spikes, bugs, and crashes. :(
negative · reviewer's own thumbsView post →Not very complicated game. Shoot, build, survive. Not much else, but sometimes simple is just all we need.
positive · reviewer's own thumbsView post →Unfortunatelly this is not what I was expecting, how come a game with such low specs can have constant lag spikes that actually get in the way of gameplay thus undermining the whole experience. Can't really recommend a game if it's at a state like this.
negative · reviewer's own thumbsView post →Great <3 Deadly 30 8/10 Heisen
positive · reviewer's own thumbsView post →Deadly 30 is a retro side-scrollers horror survival game where you have to survive 30 days. You start off controlling an american soldier character who's proficient in machine guns and are introduced to your base area. The controls are also introduced WASD to move, the mouse is used for aiming and shooting. E is used to interact with items. Doble tap A or D to leap forward. Two other characters become available as you progress: a Russian who specializes in rifles and a German who favors…
positive · reviewer's own thumbsView post →This game is a good reflection of the 'Newgrounds' Era of Games, a kind reminder of what was... It may also seem very familiar since the animator Gonzossm was the artist behind other such classics such as Toss the Turtle and the animated 'FAIL' series on YouTube, always good to see his art style. ~7 hours to get all achievements for this game, I don't ever plan on playing again but I enjoyed the time I spent playing.
positive · reviewer's own thumbsView post →1/10 meh ♥♥♥♥ game thats laggy for some reason?
negative · reviewer's own thumbsView post →Great zombie survival game, it is somewhat short but it is still great. The gameplay is simple enough it's a 2D shooter you explore left or right to find scrap and the two other characters in the game to escape. My gripe with the game tho is why is the Nazi officer a woman? that's not exactly historically accurate but I appreciate we get a playable character and they're Aryan but I wish they could be selected at the start of a playthrough.
positive · reviewer's own thumbsView post →Deadly 30 is better than having Deadly Diarrhea. Hands down, pants down!
positive · reviewer's own thumbsView post →WOW, this is hard. But still fun.
positive · reviewer's own thumbsView post →I'm ashamed to admit how much fun I had with this silly, 1366x768, 30-fps locked, grindy game in which you get to dismantle a tank into scrap parts to craft 100 wooden boxes and an alien rifle from it.
positive · reviewer's own thumbsView post →Woah, I didnt expect such a great game! So simple and and so damn fun. Even getting all achievement is enjoyable. We definetly need a sequel! (But yeah, u can get a lot of lags sometimes, be warned about that)
positive · reviewer's own thumbsView post →disappointed, I was expecting a fun game with a cool art style instead I got a game that is unfinished and keeps giving me black screen and low frame rate drops out of nowhere, sad.
negative · reviewer's own thumbsView post →Deadly 30 scratches that old-school flash game itch with its quirky WWII zombie survival setup — an American soldier, a vodka-guzzling Russian, and a German girl with a shotgun making for a genuinely charming trio. The day-night loop of scavenging scrap and then defending your base keeps things tense, and the difficulty ramps up fast enough that you actually feel the pressure. That said, the game has some real rough edges: performance issues are a legitimate problem on modern hardware, the AI…
positive · reviewer's own thumbsView post →constant lag with specs that are way above what this needs. and horrible achievements that force you to play for several hours straight to get them. because the only way to leave the game is to suicide your guys. not worth even the 5$ it costs. don't buy at any price.
negative · reviewer's own thumbsView post →This is not a very good game. It feels like a free flash game from 2004 but of the low-end type. I literally played hundreds of better free flash games on flash portals. Graphics and sound is bad. It's a zombie base defence game but I played so many better ones. This is just uninspiring, badly implemented. It manages to lag horribly as soon as a large number of zombies are on the screen, even if the graphics is potato. That means that something in the base-code was not written well. You…
negative · reviewer's own thumbsView post →Pretty great game for 55p i don't think i've even got that far into it but i like all three characters have unique playstyles and you need to think a lot about what you do each day and what you have time to do before night comes it's similar to 7 days to die but the zombies come every night instead of every 7. Overall i give this game a 9/10
positive · reviewer's own thumbsView post →It's called deadly 30 because if you play it longer than 30 minutes.. you die on the spot. This game is very unappealing, cranky controls, rough combat system, very boring zombie survival setup. There are better games on your grandma's kindle, than this piece of garbage. I am only kidding but seriously, I can't see somebody playing this for pleasure.
negative · reviewer's own thumbsView post →A really good game that is basically broken. I would 100% recommend this game if it simply worked. Somehow, this game runs worse on modern systems than it originally did, the resolution is beyond broken, it constantly freezes and speeds up, oh and it crashes sometimes (taking your save alongside it), all coming together to make a game which is impossible to play. The game is simply too broken to be recommended to anyone.
negative · reviewer's own thumbsView post →Its frustrating and hard. But its this difficulty that makes this game great.
positive · reviewer's own thumbsView post →This game is amazing. From the gameplay to the lore, this game is for casual and hardcore gamers alike. The lore is extremely rich and deep and it will keep you invested. I recommend this to anyone.
positive · reviewer's own thumbsView post →i remember watching a guy back in 2014 play this game, at the time i knew 0 english, but i still watched the gameplay becuase the game was intirguing. i thought i lost this game, but today i have found it after 10 years :D and i BOUGHT IT! still as good as i remembered from the video 10/10 very fun, and challenging
positive · reviewer's own thumbsView post →A short, but entertaining game. Shooting, base-building, and defending. Had some serious framerate drops towards the end of the game, but I enjoyed it! I also liked the artstyle and humor. A few tips: 1) Upgrade walls, weapons, and buy turrets. With two big turrets on each side (after upgrading walls), zombies can munch only on lead. 2) You can crouch, shoot and repair walls/dismantle vehicles at the same time. 3) You don't need to reach the end of the second area on each side before…
positive · reviewer's own thumbsView post →It's a rather addictive game where you'll be killing lots and lots of zombies. It's super simple, yet very easy to keep playing for much longer than expected.
positive · reviewer's own thumbsView post →this is one of those classic flash games, the "lol random" humour from this early era is extinct in modern games and is actually done in good taste, it also dosent take itself too seriously. You get a German woman with power armour, Helicopers, M60 turrets, AK 47s, alien laser guns and automatic shotguns all in 1940. Get on sale, not worth the current price
positive · reviewer's own thumbsView post →simpler days...
positive · reviewer's own thumbsView post →Game will not start, and always got stuck on a black screen when opening. Go play Toss The Turtle instead, it's a better game than this made by Gonzossm.
negative · reviewer's own thumbsView post →brings me back to "simpler" times.
positive · reviewer's own thumbsView post →literally the best game to ever be created
positive · reviewer's own thumbsView post →Looks bad, runs badly, doesn't support common resolutions and just isn't very fun to play. Avoid.
negative · reviewer's own thumbsView post →Deadly 30 is an appealing, side-scrolling base defense game where you're cast as a soldier trying to survive a zombie apocalypse. You start out defending a meager outpost that's in the center of the screen and must proceed either left or right, see how far you can make it in either direction while killing as many ugly skin suckers as possible and collecting the necessary scraps needed to upgrade your H.Q. and survive further and further through the titular 30 days. The enemies get ornerier…
positive · reviewer's own thumbsView post →i once played this game on my brother's laptop and only managed to reach day 29. Game is simple. all you have to do is survive from the zombies for 30 days. but it's not easy cuz the zombies are vary and getting stronger day by day. the con is this game was really laggy when so many zombies coming around since it used flash. and the dev already give up to fix it.
positive · reviewer's own thumbsView post →Steam Achievements cause a lot of people trouble because you seem to lose progress on some rather tedious ones. There's also a lot of FPS issues with PCs that are more modern. Probably because of the coding and sorts. I'm not bothered to look into it, going to have steam remove this from my library since I can't suffer any more of it for 100%.
negative · reviewer's own thumbsView post →Follow our [url=https://store.steampowered.com/curator/36214917/]Curator Group for more reviews Deadly 30 is a survival action game where you must gather resources during the day, then defend your base at night. It often has the feel of a web game, although definitely on the higher end of the spectrum when it comes to quality. Deadly 30’s art is low quality in a technical sense, but it has a consistent style that makes it look better than it really is. The animations are rudimentary, but they…
positive · reviewer's own thumbsView post →This game is pretty fun when it works. But its obviously got some spaghetti code running it because the optimization is TERRIBLE. A game with these graphics should run on a toaster and yet its constantly lagging at the most minor details. Maybe one day when I'm working at NASA I'll run it on one of their machines. Until then I just cant recommend, even for the price.
negative · reviewer's own thumbsView post →I also played this because it was bundle filler that had cards. The first time I ran the game, I only had a black screen after clicking Ok on the dialogue box. A couple days later, it worked on my second try. I survived a couple of nights and was glad I got killed and to have the unsatisfying experience over when I decided to explore too far from the base. The rest of my play time was idling for cards until I could as this to my list of hidden games. It looks and plays like it should have…
negative · reviewer's own thumbsView post →A really fun and amazing game. Love everything about it. Though it's short, it still features a lot of nice things, and playing as a team is also outstanding. Consider it a hidden gem
positive · reviewer's own thumbsView post →Fun game. Aged like milk sadly . Horrible settings options and Can only be played with one core or the game drops to less than 1 FPS. Fun simple kill, loot, build gameplay . Extremely unbalanced RNG can ruin the play loop rather quickly tho. For a game made by a Youtuber over 10 years ago its a great Newgrounds style game for that itch. If Gonzo took the time to update the game with an anniversary patch it would be amazing
positive · reviewer's own thumbsView post →Simple fun game, but the lag is ridiculous. It's a 2D hand drawn game, why does it have this insane lag like this? Would otherwise recommend it.
negative · reviewer's own thumbsView post →Man, what a nostalgia trip. Great game, obviously wishing for Deadly 30 second part or any alternative to deadly 30 sequel. The only complaint i had was the massive Fps/Lag spikes, constantly had to ESC/Pause to temporarily fix it
positive · reviewer's own thumbsView post →Brother if you know the origins of this game. you are a true OG and I love and respect you.
positive · reviewer's own thumbsView post →NOT RECOMMENDED - INCOMPLETE / UNSTABLE GAME STATE DETECTED! It is most telling that instead of fixing the crippling memory leak issues and the general lack of optimizing, the developers decided to have an alert box pop up every time the game boots up, telling that you have not enough CPU power. Every time a night assault starts, the game becomes an unresponsive mess that can go as long as FIVE SECONDS WITHOUT RESPONDING TO USER INPUTS. This is one of those games where you die in one second.…
negative · reviewer's own thumbsView post →Deadly 30 is a fun 2D Side scroller survival game. Even though it has Gonzossm art style, it's kind of spooky in some parts of the game not gonna lie, especially at the beginning of a run. Despite it's charm though, it has a somewhat high skill ceiling? And it's lacking on the replayability department, all of the achievements is obtainable in one sitting (not that I'm complaining). Overall, 28/30 nights, would survive again.
positive · reviewer's own thumbsView post →Deadly 30, developed and published by Ignatus Zuk and Gonzalo Villagomez, is a distinctive blend of side-scrolling shooter, survival management, and tower defense that sets out to challenge players with one simple yet punishing goal — survive thirty nights in a world overrun by the undead. From the outset, it wears its indie identity proudly, offering pixelated 2D visuals and a minimalist structure that harkens back to classic Flash-era games. Beneath that straightforward presentation, however,…
positive · reviewer's own thumbsView post →BUYER BEWARE: this game is good for a bit of dumb zombie killing fun, definitely worth the price, gameplay loop is enjoyable and the art is good. However the game is loaded with performance issues. I mean the game will be borderline unplayable at times. I play on the lowest settings though and it still looks decent and is fun so I'd still recommend it overall.
positive · reviewer's own thumbsView post →Great game for its time and price. The only criticism I have for it is the lack of settings. Edit: The game has a leaking problem, you I have to re-open the game ever 2-3 (in-game)days. Otherwise the game will keep having LARGE slowdowns...
positive · reviewer's own thumbsView post →No steam cloud (which means you need to handle backing up your game file yourself), game does not save graphic/resolution settings, game does not tell you that you that any weapons you buy/purchase/find/unlock is for other characters you find/come across (apparently, their are upgrade's for your main character, and i came across one, but my character did not equip it even after i bought a bit of each ammo type). Scrap is few and far between. You have a small amount of time to travel to find…
negative · reviewer's own thumbsView post →Game is really fun but is borderline unplayable, i haven't had it crash yet but it constantly lags after a few rounds no matter the settings
negative · reviewer's own thumbsView post →I got Deadly 30 for a dollar, about what it's worth if stretching the good parts of it further than they actually go but I'm a sucker for nostalgic flash games. It's not worth the $5 asking price, it should probably be free as a cool proof of concept that the devs use to show that they're ready to make a full game, and the faults are so severe I can't argue with the negative reviews. But hey, get it on sale or not if you're not as much of a curmudgeon as I am, it's a fun afternoon for a few…
positive · reviewer's own thumbsView post →I am 32 years old. My ex-wife and I have a daughter together, and we adopted our son together. Both are now 4 years old. When we were going through our separation, I felt lost and unhappy. I was self-destructive. One day, I was so angry with everything spiraling out of control that I punched a concrete wall in a moment of overwhelming emotion. This resulted in breaking my fifth metacarpal in my right hand—the hand I worked with, played games with, and used to carry my children to bed—the hand…
positive · reviewer's own thumbsView post →Deadly 30 pros: //fast game with modern day graphics with easy controls that moves from location A to B to C and so on cons: //a lot of difficult battles //some enemy AI are overpowered //not enough time to explore and collect resources //weapon resources seem underpowered //good game Personal Suggested Purchase Price: Free To Play
positive · reviewer's own thumbsView post →Deadly 30 is a small and fun mix of zombie survival-shooter and tower defence game. It can be quite challenging to begin with but don't give up. The goal of the game is to hunt during the day for scrap metal and head back to base before the night to buy upgrades and defend it from a zombie horde. Character experience points gained unlock new weapons, defences, and items as you play, and it carries over to new playthroughs. The gameplay loop is enjoyable; killing zombies, finding scrap and…
