Reviews
A good idea for a game but poorly designed Cant even run the game at 60 FPS when I have a 4060 TI 16 GB Vram 32 gb RAM Very unstable crashing is prone.
I saw a video of this game and thought it was amazing although I'm not a big RTS guy. Read some of the reviews and the one from Danger Desperado specifically kind of put me off a bit. Went into the forums and talked with the dev and ended up buying it to try with a buddy. Happy to say it has so many customizable options that you can play it how you want. It definitely didn't feel like any other RTS I've played and was a very unique spin from a sort of city manager mixed with troop management and then the attacking. It was pleasantly really well done and smooth. Experienced no crashes or bugs and basically if you want to spend a few hours playing with a friend or a few just clearing out a city of zombies this is a very fun original RTS take. Definitely will be playing again with the sliders adjusted and some of the other maps (we played on the older first map).

This and every other Pro feature is free until October 20, 2026. A free account is all it takes.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 25 chart moves that followed a price cut of more than 20% went a median of 10 places towards #1, and the 2,413 moves with no price cut behind them went 2 away. One store, one chart, one country — it is the only place we have enough observations to say even that.
Prices outside the United States have been collected since 6 August 2026 and chart positions since 19 July 2026, so a cut older than that has no market to compare and a market that joined later has no history yet. Nothing here is converted between currencies.

Slop
Cool in concept, awful in practice. Performance is extremely poor across the board. Loads of issues. Sluggish development. No real progress. Currently unplayable as it crashes constantly, even in the menu
Huge Mess
Game is currently in active re-development with a lot of improvements and changes from the first iteration. It's exciting to watch this game grow and the devs are constantly updating the new version. The old version is still playable, but it's slowly becoming obsolete with every new update.
It's slowly taking shape. Playing in coop offers the most fun, just don't forget to turn the "birds" off, or at least tune it down or suffer the 1-5 fps slide show. (As of now winning with default settings is infeasible.)
6 years and still in early access no tutorial no campaign i refunded and ill check back later if they ever actual finish this game
Optimize it better pls, im trying to enjoy the game but i cant go to the bigger maps without the game just crashing randomly during the playthrough, i can run the game fine at a solid 30FPS but its usually when there's to much models on screen like the zombies or there's to much goug on like gunshots or explosions, or destruction the game decides to give up. YES i play the game on low graphics but its still crashes happens often.
