PLEASE NOTE: THIS GAME HAS BEEN ABANDONED. DEVELOPERS ARE WORKING ON SEQUEL. The game is really fun. By far the best Tower Defense Base Building FPS out there. Graphics are pretty good so it is recommended to have a "Better" PC. The gameplay loop does tend to get repetitive after a while until you start fighting different bosses. I've had a blast building my base even though it does take a while to farm all the things you're looking for.

The game definitely does not deserve Mixed reviews (while its only recent, not all time). I love it, its not easy, every failure "tour" is a consequence of overconfidence (mostly my cases) and poor preparation, which forces you to upgrade your base over and over again. But everything is doable! First of all I was thinking it's a tower defense. But it is not. It's more session looter-shooter with defending your base in the end of every session where the fate of the extracted resources is decided within a couple of hours. And it hit hard to ego when you fail. Because mostly you don't understand why you failed. But its mostly your overconfidence. At 65 hours I'm not close to end game, so there are still many hours of grinding and base defending. And there is announced already Outpost 2!

This is not a perfect game, but it has enough cool mechanics and gameplay to be worth it in my opinion. It is a cool combination of looter shooter and tower defense I've seen nowhere else. The amout of dakka you can send downrange towards the enemies is insane.

Janky, non-sense story, terrible voice acting, glitch ridden, bug infested, no hand held hot mess of a game. Got it on sale, the campaign sucks, but there is a fun gameplay loop to be had and thankfully it has wave and survival modes. Multi-player is dead. Game is technically abandoned for a sequel. The fanbase/interest for this game is tiny/non existent, you will be hard pressed to find any useful information to better your playthrough experience and will be one your own. Best way to describe the game is a fps/rts with a persistent base you build, collect, craft, then expand to take on harder content. The wave/defense aspect is fun, the rest is either a chore (manually collecting loot, early tech restrictions) which will turn into a grind, or downright cringe (voice acting, gooner ai sidekick(wish I was joking), odd humor/tone shift, highschool level cinematics, animations and story) My suggestion is have subtitles on, use the native Chinese vo, and your own music. Why recommended? I love janky dumpster fires. This garbage scratches the itch left by Earth 2160 and dare i say surpass Reality Pumps ability to shamelessly release a gold-leaf plated Turd. 10/10

July 2025

I have over 200 hours logged in this game, between playing alone and in coop. I would say if you like tower defense games or top down RTS you'll enjoy the game, you can build your main base up and turtle inside it letting the base do all the work while your build external defenses or command a army of robots you've built and deployed during the campaign. The biggest draw back for most players is having to loot the entire map every time you progress to a new section. But honestly you don't have to do this and certain gear makes it easier and faster to travel around the map like the grappling hook and area scanner. Things you are not really able to make use of or acquire until later in the game.
