Not recommended Jul 5, 2026
I don't like negative reviews.. but the videos... do not match your general gameplay. You get part of those videos in the 1st part for the story. After that.. generic areas.. basic tower defense... poor resource gathering... copy/pasted content.. terrible layout.. over complicated basics... terrible.

First off, the game is incomplete, yes its missing allot of storytelling aspects. On that note, the storyline is @$$, dialogue is just as bad and don't rely on the tutorial too much, this game is a very indepth game with many twist and turns and hidden mechanics. Many glitches where items fuse into the maps and you cant reach them because of the. If you go exploring and decided to explore that one small spot that looks interesting and you fall into an undeveloped trap and can never come out unless you have specific gear and equipment to help unstuck yourself.

You need to farm for resources to improve your mobile outpost and you can design it however you see fit for your own taste or functionality. Yes indeed it takes time to understand how the game works because there is so so much to learn. From Operator base management, to resource gathering, to Tower defense apect, then the First Person aspect when you golooting for materials and resources, th…

Addictive gameplay loop building big guns is fun! Operator FPS combat is pretty bland, building up your outpost is fun even if the loot tiles get repetitive relatively quickly (same issue with all extraction looter/shooters).

Game is extremely fun if not a bit reptitive, wanted to play a tower defense and i struck GOLD!!!!!!!!! Got locked in a couple story missions, a couple times needing a restart, but other than that game has run pretty good, no crashes yet or anything.
