good developers dedicated to their game latest updates are super good
Highly underrated RTS, you might wanna rebalance the birds though, they chew units and juggernauts make it hard to gain ground. You might say its a tower defense, but really its not. In all actuality, it is a pure RTS at its core. I love the game, some polishing of the animations and more unit sizes would make this more of a blast. It gives me Resident Evil Umbrella Corps RTS vibes. It's hard to make a RTS that checks the boxes like this one does. Gameplay 9/10 - Intuitive UI 8/10 - Gets the job done and is pretty enjoyable AI 8/10 - Further fixes and it will be amazing Enemies 7/10 - Bird swarms and dual juggernauts with base stats will have you praying Environment 8/10 - Further reworks or changes to it, will make it amazing. Overall: 9/10 - Plenty to do and addictive, keep the RTS form factor since this is purely what makes it appealing to me! Bugs: Sometimes units will freeze in place or not follow orders, then again I played at higher units. Needing reworked: Contextual animations, AI, and enemy balancing

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 26 chart moves that followed a price cut of more than 20% went a median of 7 places towards #1, and the 2,400 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.

I'm REALLY like the combat, especially the customisation!!! its scratching an itch ive had since warzone 2100 days, but as of now, the pathfinding is killing the potential of this game. Units will freely allow the enemy to completely overrun your base before deciding if they want to move to where you ordered them too 5 mins earlier because either they have to drive around 1 obstruction and just seem to become completely lost to the point that you may as well delete the unit all together and just re-buy it, or because there is some sort of conflict with mixing soldiers and vehicles. The devs have done an increadible job, and if they can get the pathfinding to be more responsive instead of suffocating, then I may have just found my new RTS addiction.
Nagyon még nem mélyültem bele, de a szigetes mappon túléltam vagy 3 napot mire fűbe haraptam, kifejezetten a kampány módot várom nagyon, remélem kiforrja magát lassan :) nem rossz zombis rts stratégia lesz ez :)
They have a great idea and I like the direction they want to take the game, how ever even for a pre release game it feels extremely clunky to put at best. UI can be really confusing and some game mechanics feel very unexplained and difficult to figure out. Also it keeps crashing extremely often which makes me have to jump back into my latest save and replay the last few minutes only to be able to continue for a few more minutes. Should not happen. I'm running it on a rtx 3090 with 13th gen i7. I can play cyberpunk but not this...
SO ♥♥♥♥♥♥♥ GOOD it crashed tho
Man merkt das es noch in der early ist aber trotzdem sooo gut ! lange kein spiel mehr gehabt was mich so vor dem pc gefesselt hat ! Viel stufen von Erforschungs Möglichkeiten, Gameplay tiefe absolut vorhanden. wer auf shooter mit Taktik und Basebuild System steht Abolut richtig hier !
Took a little trial and error to learn the game mechanics but if you’ve played anything like C&C it should be quick to pick up. I will say that I SUCK at this game. I evacuated less than 250 people in a city of 50,000 but it still a blast. It’s really cool to have a hero character you can customize and control not just in RTS but also over the shoulder. As far as performance, I don’t have anything close to a top of the line rig and I still get good performance.
Macht Spass, auch wenn der Technische Stand gefühlt wie vor 2 Jahren ist, weil man das Spiel auf neuer Technik neuschreiben wollte...
Amazing game with great potential. I like the customizability
