    I had a random flashback of this game from some ~20 years ago while watching an episode of One-Punch Man... But it was more like a feeling than a simple memory ? Or a memory accompanied by a physical feeling ? Weird. Anyway, best game ever, 10/10. I feel like a kid again ^.^

    My beloved childhood game. It's pretty simple, but unique and a lot of fun. I was thrilled when my mother bought me the CD with Impossible Creatures. It felt so cool to combine different animals into amazing mutants. Even today, this game can surprise you. Scenarios with Velika La Pette were my favorite!

    There is a unique charm to this game that manages to overshadow the game's glaring issues of single player and multiplayer balance, bizarre design decisions, and unrealized, questionable intent with the game's mechanical identity. I'm going to be real, this game is unbalanced in many respects. Some unit combinations are utterly broken. Single player campaign is dominated by unfair AIs with massive bases that grind every mission to a screeching hault. The electricity resource is so plentiful…

    Well… good. This is an RTS game. The graphics are dated but decent. The music fits. The story is funny, and there’s a clear effort behind it. No bugs, no crashes. Overall, entertaining. The main appeal is creature mixing and experimentation, which offers plenty of strategic variety. On the flip side, it suffers from the usual RTS flaws: imbalance and occasional chaos. Speed rules everything; fall behind even slightly, and recovery is unlikely. Not much chance to enjoy the scenery. Rage-quits…

    Might be the most unique and creative game I have ever played. Nothing beats the erly 2000's gaming era. One of my few childhood games I play year after year when nostalgia hits.

    There's actually zero good reason why an RTS game with mix and match units that combo parts together for different abilities, completely unique, gets left in the dust. No sequel, no remaster. We just keep getting spoonfed the same "modern" ♥♥♥♥, but you can tell that this was made in the classic days.

    What If You Put a Shark on a Praying Mantis? There are games I remember because they were great. Then there are games I remember because there was absolutely nothing else like them. Impossible Creatures is the second kind. The Best Part Was Making Monsters The entire premise was wonderfully ridiculous. Take two animals. Combine them. Create something that nature absolutely never intended to exist. Want a lion with the body of a scorpion? Go for it. Want a praying mantis with shark…

    I wish they make a modern remake for this game. Amazing implementation of army building features and one of the most unique RTS games ever made! It is a bit basic in some of its RTS elements though.

    Fantastic game! If you don't mind 2003 graphics, it is a brilliant game with great mechanics. I played this back when I was a kid and I am an adult now, still love it. The DLCs people have made, make it extra fun and the maps people have designed make it more entertaining, especially when you have learnt all the original multiplayer maps like I have. I have played the campaign countless times and it is so much fun, really ♥♥♥♥♥♥♥ hard at parts [the multiple factory mission] and interesting…

    Should be a cult classic, but too obscure. I Hate every RTS game I've ever played simply because I started with this one when I was a kid, and in creativity I think it's still unmatched. Make sure to play with insect invasion content enabled if you're just messing with the creature creator!

    Impossible creatures is a wonderful RTS game, where you design your own units by splicing animal bodyparts. As a child, I spent hours mixing animals for the fun of watching the weird hybrids bounce around on screen, and I also loved the story campaign. Comming back as an adult, I am really enjoying the player vs player aspect. It is a fun RTS battle game, and between battles you can re-think your monster selection and get a kind of deckbuilding style kick out of that. The economy system…

    Impossible Creatures is a real-time strategy game that has earned a lasting reputation as one of the most imaginative and unconventional entries in the genre. Originally developed by Relic Entertainment and later reintroduced to modern audiences through THQ Nordic’s Steam release, the game stands out immediately thanks to its bold central idea: instead of commanding predefined factions with fixed unit rosters, players are encouraged to design their own armies by splicing animals together into…

    My neighbor had a copy of the demo she gave me in 2002/2003. Played that demo endlessly. 20 years later and I bought and beat the full game for the first time. Such a massive hit of nostalgia! If you like old school RTS, this one is well worth the $10.

    There are some visual bugs from time to time. Luckily nothing major. The game is still as fun as it was all those years back. The campaign is very well designed and quite engaging. Really wish we got Impossible Creatures 2 one day, where you can combine up to 4 creatures and have even more control over what is modified, but I doubt that will ever happen given the gaming climate. Who knows tho, one day maybe

    mpossible Creatures was one of the most creative and fun strategy games of my childhood. Its unique gameplay—letting you combine animals to create bizarre, powerful hybrids—was both innovative and endlessly entertaining. From eagle-tigers to shark-wolves, every battle felt fresh and unpredictable. The game’s wacky tone, combined with surprisingly deep strategy, made it a standout experience that I haven’t seen replicated since. If you’re craving something inventive and unlike any other,…

    I hate myself. Everyone abandoned me and for what? God has made us just to give us freedom and what do I do with it? Ruin every relationship I've ever ♥♥♥♥♥♥♥ had, ruin every love I'd been given to throw it away for nothing. Only to lock myself away in insanity and discomfort to tell myself I'm free and happy letting out my emotional instability to destroy and create abominations of absolute agonising pain to display my dissatisfaction with myself. FOR WHAT? NOTHING CHANGES. Fun game:3! Try it!

    This was my childhood game and the nostalgia hits hard playing it. It is really fun to build your army and annihalate everything with a wolverinXPotwhale all the time. On the other hand I think this is one of my favorite RTS stories and the steampunk aesthetics are on another level. Of course the graphics and controls are a bit outdated nowadays, but it's still a fun time to be had

    The game that got me into RTS. I have so many good memories. Just the sheer nostalgia effect is just delicios. Anyhoooo: 1. The game lacks any real graphical updates for the modern gamer. It has good graphics for a game over 20years old. 2. The campaign story can be rather deep, and at times comical, it has an air of new discovery vibes. 3. The defensive towers are rather standard and not too deep. 4. The real winner is the creature combiner for your armies. It can have you barreling over…
