Reviews

Explore reviews from Steam users sharing their experiences and what they love about the game.

Dec. 2024

The game is fun. It feels like playing Prototype as an RTS, and you're on the side of the squishy humans. Also, the people complaining about the "DLC" are crazy. It's literally an art book, a novella, a comic, and some two dollar skin packs that are explicitly for people who want to offer more money to support development. None of that is taking resources away from development to get money.

Oct. 2024

I really would lean more towards a neutral rating if possible, but between positive and negative it's definitely the former. The game itself is decent fun right now, and is absolutely worth picking up for $20. But the fact that it's early access is apparent, it is most definitively *not* a fully realized game, so don't go in expecting that it is. The developers are making slow but steady progress, and they've been very interactive with the community, not to mention super easy to reach out to. A lot of problems seem like they'll be fixed within about ~6 months here, so if you're willing to play an unfinished game and act as a tester it's worth picking up, otherwise check back in every couple months. (And if devs see this, I know I've mentioned it before, but the UI is really missing *something*, just not sure what).

Sept. 2024

I see many developers who drop a great concept after a while or disappear quietly and secretly. The boys and girls carry on listening to what you say. I like the game the concept is great but oo boy the performance really needs to be better the FPS likes to die.

Aug. 2024

A janky ass game that's still got a long way to go, but I love it. The devs are very open and willing to listen to feedback, the game is very fun to play especially building up a massive fortress and saving civilians, fighting zombies, etc. But most of all, the game lets me live out my childhood dream of a game where you play as the military and fight zombies and save humanity. Somehow, very few games have attempted this.

Feb. 2024

I’ve definitely enjoyed it, it’s not too long form, but there’s plenty of variability in how it plays to make play throughs 100% worthwhile. The open world is looking pretty cool, the game have a system of specialization like company of heroes and this give you access to new units and buildings. I’m really looking forward to the coop mode. Overall it's a good game , some things can be better. Definitely worth the cash and they’re working hard to keep improving, have a clear road map and are communicating really well with the community . Solid 9/10 Some bugs here and there but still, it's enjoyable
