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

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.

TL;DR This game has some rough edges. There are some places that could use another dollop or two of polish. There are some consistent bugs and some inconsistent bugs. But it's a good game. Let's start off with the negatives: In terms of bugs, there are some loot items that always spawn in inaccessible locations in certain levels. They'll show up when you do a scan for items but they'll be inside part of the environment and nothing I could think of to try will ever make them move. There are other intermittent cases of loot either spawning or falling into the environment, and sometimes these can be recovered by walking back and forth over them until they move (this solution has a better chance of working in multiplayer as sometimes walking over it won't make it move for you, but it does for the other player). There are some rendering blips where things like trees or ore will either not be visible until they're approached, or will be visible only until they are approached, when they vanish. Very occasionally, something more severe like getting stuck in the environment or stuck in character animation so that you can't interact with things. There is an even rarer crash-to-desktop bug but personally I've only seen this in multiplayer when returning to the tactical map room and we've never lost progress as a result. It does seem to mostly rely the ol' CPU though. If you have an older or budget processor you might see some stuttering at the start of a level. In terms of polish, the voice acting feels like an early effort in terms of dramatic acting and gravitas. The text in the game is also a bit hit-and-miss with descriptions on some of the XEN items being nigh-inscrutable and other clues here and there that the developers were not working in their first language. None of this prevents you from playing the game, and honestly I find that kind of thing endearing mostly. One character in particular was kinda grating on the ears but they don't get very many VO lines. Some of the basic mechanics of the game aren't explained or I just misunderstood them, which I didn't know until I started reading stuff in forums. Sometimes the images on items in inventory will suddenly scale way up or way down making items look strange. The AI is serviceable but pathing is easy to confuse and it's pretty rare to lose to an enemy because you were outwitted. You do reach a point where the sheer might of your mobile fortress makes it pretty hard to lose accidentally to the boss waves. This may be related to the truncated roadmap I've seen other Steam users griping about in the forums, but that is only a guess. Now the good parts: It's fun. Moving around the world feels pretty good, especially once you get some of the mobility gear like grapple gloves or double-jump boots. Shooting looks, sounds and feels impactful. Assets are good looking, though not entirely consistent style-wise so it wouldn't surprise me if some or all of them were purchased rather than developed in-house. The variety of gear and loot and the pace of progression are also tuned to be satisfying, at least to me. It pushes the right dopamine buttons at the right times to keep me playing for ~185 hours so far. Building the base during down time is entertaining, and how you put things together has a tangible effect on functionality. When you unlock the next thing it is very clearly worth upgrading to, even if you're going to have to redesign your layout yet again to incorporate it. As I mentioned there are rare crashes here and there but the game was really good at saving progression so that you could get back to what you were doing relatively quickly and painlessly even in multiplayer. There is surprising variety and depth in the gear and skill systems. You can completely switch how your character plays by swapping around a few armor pieces and some XEN... patches? They're equippables for your gun. There are synergies to exploit and anti-synergies to discover and despair over. Talking about skills, there are four different "classes" of operative that you can add to your roster and play with, each with a basic set of core skills that is standard to that class and a variety of mix-and-match minor skills that are randomly generated when the operative is recruited. There are passive missions called "dispatches" that you can assign operatives you aren't using to complete for small rewards and also to gain experience and level said operatives. There is also a research system to unlock upgrades and new components for the mobile base. It starts out as a small one-room outpost but grows over time. At the time of writing this mine is an enormous triple-decker juggernaut bristling with guns, cannons and missiles. I have definitely gotten my money's worth out of this game and I suspect I'll put still more hours into it later, perhaps on a new save or maybe just to see how big I can make my base. There was clearly a lot of effort put into it. None of the bugs were so frequent or so severe that they seriously interfered with playing. Those same forum posts griping about the roadmap mentioned that the developers have declared their intention to make another game that learns from the mistakes they made in this one (which supposedly led to things falling off the roadmap, etc. but again this is all hearsay) and if they do I will definitely be excited to check it out. If you're made it this far and you think you'd like to play, I have some hot tips. 1. The contents of pack mules ONLY get recovered if you move them into the dropship with you before you leave. They can jump, get them into the green zone. 2. Core output is a big deal. Like, a REALLY big deal. If you find yourself struggling to survive on recovery day you probably need to work on that. 3. If you're playing multiplayer, try to make sure one of you picks an operative that buffs resource collection. It really simplifies things with longer tours. 4. You can do a lot of stuff faster and/or from a distance in command mode. Poke around a bit.

Me a 3 friends played this for 50hr straight, over a weekend. What a strange and wonderful experience it has been to get to know this game. It opens really slow and takes ages to get to a point where the game allows you to just play and have fun, It is outfitted with one of best collections of gameplay mechanics I have experienced in a long time. And it also manages to hide that away behind a 3 hr. tutorial that feels like a deliberate attempt at sabotage. Still, I would recommend this to anyone who is in to games with genuinely unique and novel gameplay mechanics. Just get over the tutorial, if you want to play with friends.

WARNING!!! Deciding to buy this game should be based on how much you enjoy spending hours moving thousands of pieces around to build a base structure that may not work. Enemy AI: F'n BAD Map variety: very low Story: exists. Acting: is bad Grind: long and tedious Tutorial: poor Learning curve: Above average Optimization: Poor But hey; I have spent that time to build the base and I'm still grinding. So apparently; I think it's a game worth playing. Or I've been hypnotized. you pick.
