What people are saying

Mostly positive Early Access bullet heaven with solid foundation but some balance and variety issues.

Players praise the polished gameplay, good power progression, and fun factor, calling it a 'worthy survivor game' with 'all thrills no filler'. The stylized 3D urban sci-fi visuals and smooth performance are also highlighted. [1][3][4]

Critics note it's a basic Vampire Survivors clone with lack of weapon synergies, unbalanced weapons, and a grindy progression. Some report bugs, abandoned development, and poor Steam Deck support. [28][30][33][35]

    A very good foundation for this Early Access bullet heaven title. The stylized 3D urban sci-fi vibe and look works out well, with an already polished and fun gameplay and a good power progression. It's a bit closer to those slow bullet heaven titles where the player is outgunned early on, but the movement speed and health levels mean it's feasible to properly crowd control large amounts of enemies with the correct weapons and perks. The game only launched today, at the time of this writing, and…

    Mediocre survivors like game, abandoned in Jan 2024 with unfixed bugs. The game includes ~ 15 hours of gameplay (doing missions with different diffuculty settings and unlocking new weapons/passives) - 1 broken achievement ~ 3 expremely grindy achievements, 1 of them will take hundreds of hours - broken reroll system - lack of variety in builds: you want ion shield, armor and vitality upgrades as well as all AOE weapons every time, otherwise you cant beat the levl with modifiers - boring boses:…

    Very raw. I can't imagine picking this over other wonderful titles in Vampire Survivors genre. The game is not fit for Steam Deck and barely playable there.

    It's Vampire Survivors with poly graphics and a (in my opinion) blander scifi setting. Upgrade path is good and you can achieve that frenetic feeling of popping lots of mobs. Feels a bit harder starting out and the unlocks more expensive... maybe needs a little balancing toward less initial frustration. Recommend if you like this kind of game

    Pretty barebones Vampire Survivors clone. What Easy Target said in another review here is pretty obvious even early on: you either go for Vitality + Armor + Ion Shield or you won't make it. After some 8-10 minutes in (or every set number of levels), you'll get a warning for an event. Complete it and you'll get a crate - sometimes you also get all the experience scattered around, but I have no idea how/when that triggers - which is very underwhelming in how it opens. It shakes violently and…

    Boring Vam Suvrivor Clone, it's so bad, so boring, so bare bones. If you're behind structures, you're screw, you can't see what's coming, what's around you. And get ready to get stuck on unnessary objects, you're "Holding" the objectives, but very well, those blockages possed a threat even to you. The Menu? The UI? they felt so outdated, not even user friendly. The only thing i like is the Visual of Skills effect

    This is worthy survivor game. It have the now popular polygon assets with good visual effects. There is alot of unlocks what tied to quests you have to finish in missions. Very fluid and fun gameplay, alot of characters and skills to unlock and choose from. They also keep contact with the community and working on next Update. It have a demo what you should try. Recommended game!

    TLDR: Pass on this, buy a different vampire survivor clone. There is just no depth to this game. No weapon synergies. let me repeat, there are NO SYNERGIES in this game. that already takes away a huge portion of strategy. there are no 'builds' in this game.. There are only like 2-3 good weapons and you will buy them every round. The progression is also super grindy. You have missions to complete which sounds cool, but they take a long time and aren't interesting, most are just pick up X of…

    There is an extreme lack of variety in weapons/abilities compared to most games of this genre which makes the gameplay too repetitive. Combined with how lackluster the upgrades are, it makes the progression system too tedious and boring. At least it's really cheap.

    I want to like this game but I wouldn't recommend it unless you've played every other game in the genre. PROS: -$4.99 price tag means that if you got a few hours entertainment out of it then you got your money's worth. - Good graphics for this genre. CONS: -way to easy. - unbalanced weapons. Some weapons are too weak and some are two powerful. It makes picking or not picking items at level up a no brainer. You're not going to strain your brain at level up trying to decide what to pick.…

    This is a mostly competent Vampire Survivors knockoff. Play sessions can be much shorter, ranging from 3-20+ minutes instead of mostly 30+. Some starting weapons do not feel useful enough to facilitate survival, and maximum movement speed is still quite slow. I've only just unlocked the 3rd area - Atlantis Lab.

    Defend Earth: Xenos Survivors takes a familiar survival-action formula and places it within a large-scale science-fiction conflict where humanity faces overwhelming alien forces. The core idea is immediately recognizable for anyone familiar with survivor-style roguelites: enter dangerous battlefields, survive increasingly aggressive enemy waves, gather upgrades, and slowly evolve from a vulnerable soldier into a devastating force capable of clearing entire screens of enemies. While the genre…

    The environment is an interesting take on bullet hell/survival games. Well, mostly. You are in a world where aliens have invaded. Your primary task is the saving of the planet. This means that you need to stay alive as long as possible, collect items, die and do it all over again. Given time and enough playing and you might just make it. First, the graphics are quite nice and game play runs smooth. You will eventually start finding health, but be careful because the location of med-kits are…

    It's another VS inspired game but much prettier and slower. The slow speed makes for a much more interesting game. The creeping horde is intimidating if you haven't got the right build yet. The 2 maps available so far make for great use of environment to manage hordes and find hidden xp . The power builds are what you would expect from this genre. One criticism of this is when in horde mode you stop powering up your weapons after 10 minutes, leaving another 10 + minutes of collecting points or…

    Great fun going through these waves of enemies thrown at you. While it starts easy enough, you really need these upgrades to get through the increasingly more difficult hordes of enemies. The first boss comes with dozens of smaller enemies that try to get at you. As each level does not take too long, you can easily squeeze in a session.

    Already playing this game since closed beta and i'm really happy about the early access release yesterday. Since my first playthrough the team behind DEFCON: Xenos made some major improvements like an additional map, new enemies and new weapons. The second map is vastly harder than the first one and i wasn't able to finish yet, but especially because of the increasing difficulty it makes the game long lasting and really fun to play. The team sure has to optimize some things, but all in all…
