“I don't understand the hate this game is receiving. Already I can see a massive improvement from the EA days to now. Gamers have way too high an expectation of games these days. Seriously, there's something to be said…”
“A very good game. I started in early access and with each major update I restarted it from the beginning. A complex game: survival, construction, unlimited exploration, 5 research areas... over 300 hours of play and…”
“The game has some rough edges but is already very enjoyable. You can start with nearly nothing and you have to get to the point where you are self sustainable. That is the most fun part. After you are basically able to…”

“The game has a very large area, the mechanics make sense. It can be a grind to unlock everything and the Chem Lab makes unlocking even more time consuming .. but I find myself addicted to the game. More bugs than I like…”

“Cannot wait for the Actual 1.0 Release, because this ain't it. It still feels like a 0.3 Build, it's buggy, it's aggravating, and the progression is so slow it makes me want to perish. Rumors are the devs are spiteful…”
“I have tried to like this game, but as of release it is janky, buggy, and has some real design flaws that go beyond the unity engine. The Good: Graphics are mostly good, though most of the models feel like they are from…”
“Took me a while to workout the best things to unlock to best setup my base, but well worth getting. Graphics are good and gameplay is pretty awesome. Remember to use the workbench to upgrade your tools once you have it…”

“Most of the 'challenge' in this game is pointless grief from the devs. The controls are clunky and annoying. The game regularly hitches. If you want a better space base building experience I'd recommend Stationeers or…”
“Game is horribly buggy and slow. It is basically still in an EA state. Main parts of the game not or just barely working due to bugs. And you still run into things where you have the feeling it is still WIP. On top (on…”

“Not a pleasant game. First and major complaint about it is: no captions. In today’s day and age not having accessibility features is just ridiculous. Also… just needs to be polished. It feels cheap and unfinished. The…”

“★★★☆☆ Occupy Mars: The Game — 120 Hours Played After spending 120 real hours in Occupy Mars: The Game, I can say it’s a decent survival experience with a lot of potential, but also a long list of issues that really hold it back. What works The atmosphere is great and the early…”
— a player, Steam review · 128 hrs played“I have been playing, almost exclusively, Co-Op. My overall opinion is this game is going places. I want more. Are there problems? Yes, but things are being fixed. It's clunky but enjoyable. Occupy Mars has so much potential and I am going to enjoy the ride.”
— a player, Steam review · 161 hrs played“I was playing Early Access in 2023. The game has great potential and I was happy to discover that it has now been fully released as version 1.0. I immediately got back into the game and put another 100+ hours into it. Sadly, the 1.0 release was rushed. Even as at version 1.0.12,…”
