If you like horror co-op (like I do) ...and you've played a lot of BAD horror co-op games that look okay in a trailer but are no fun once you actually play them (like I have) ... then do yourself a favour and GET SPECIES UNKNOWN. At its current price it is absolutely absurdly good value of entertainment for money. Round up a few friends and just go in blind. Less research is better; unlike most games in this genre, this game will give you all the tools and information you need to survive and win, but will never hold your hand. It's polished, it's immersive, they CARE about the little details. The different monsters are actually truly different, completely separate experiences every time. Teamwork matters, communication matters, planning matters, and thinking fast when ♥♥♥♥ hits the fan matters. Do yourself a favour and just GET THIS. I felt I had my money's worth after 1 mission because it was so intense and fun. Everything since then has been a bonus. Long, long term, you may find you want more content. I already kinda do. But with this game, I want more because what is already here is SO DAMN GOOD. It's very worth it. I have gone through a lot of coal in this genre looking for a diamond; now that I found one, save yourself the trouble and just take it. Trust me, it's worth it.
Absolutely excellent, similar format to other games such as forewarned and phasmo but with an alien isolation vibe, very high quality with incredibly graphics, only caveat is that in current state it IS a little light on content, only 5 monsters and 1 map. BUT assuming they stay the course and keep things this good as they add more monsters and maps? potentially one of the best horror co-op games on the market!
Don't let a cursory glance fool you, this isn't an asset flip. This is basically casual Alien Isolation, with many aspects of the xenomorph split into different monsters, and a few added on to add variety. Biggest highlight is playing with friends, and the game actively utilizes teamwork with items being useful in tandem, but you can only take one item per person. Basic teamwork, sure, but it's good and works well to kill the idea of "Optimizing out the fun". Noteworthy bit, too, is that information is a weapon used against the player. The only place to learn about monsters from the start is on the "Mission" ship, when you're already in the thick of things. You need to basically hit end-game to get access to a calm location to study the creatures you'll be facing, at which point you likely only need the exhibits for reminders or novelty. A+ information economy
