“Yesterday i played around 7h and I like the game so far. A few parts in this game feel a bit like eve online. You have to do something to collect your xp to get a skill leveln. You learn the skills like in eve, you buy…”

“Ok After 65+ hrs time to review. I nearly didn't try this game, mainly cause of the massive amount of neg comments about P2W and overall "fairness".I am thankful at these times i make my own choices and not follow the…”

“It took the patience of playing EvE for a late game payout I am thoroughly enjoying. Intricate tactics coupled with a mysterious set of mechanics that encourages cooperation. No pay to win in sight. Be mindful of…”

“Though I love Tactical turned based games and post-apocalyptic scenarios, this one is very hard do like. First of all, don't let the name fool you. This one plays more like a survival game in isometric turnbased mode.…”
“This is a nice Free To Play game where you can have some fun without having to pay money. The interface is easy, the graphics are good enough and the statics and item descriptions are helpful. I don't like the timer in…”
“UFO Online: Invasion is a a Free to play turn-based tactical combat MMORPG set in the post-apocalyptic world. I guess you could compare it to fallout or x-com. It worked, looked ok, sounded ok, played ok, was…”

“Nope, not this game. There are too many flaws to make this game playable for me. This is a major grind fest used to leech money from players who prefer Pay To Win. This is a horrible imitation of X-Com, has time…”
“This Game is Terrible Just another generic browser-based strategy game; except this one is worse. I get that this game is "new"; but that is not an excuse for it being nearly unplayable. The game is very glitchy. I…”
“A very... Meh~ game. I played it for only about 20 minutes and it made its first impression the best it could. The good things are that it doesn't lag The bad things however (although most of these are probably opinion…”

“This game is UFO: Aftermath with one persistent character, no controllable squads, no realtime strategy, no base-building, lots of grind, a multiplayer chat and none of the fun. Not worth the time.”

“Since I played 20 minutes only, I cannot make decent review. However, I can tell you my impressions based on 20 mins gameplay. You should download the game 100% It is better than XCOM 2. Not :) Not better.. Not even…”

“Decently fun, though the devs state in the official forum rules that they'll ban people that disagree with them, which raises a lot of red flags for the future of the game and the community. Cautious recommend for now.”
— a player, Steam review · 4 hrs played“I haven't played too long. But enough to know that the reviewers below are being a little harsh. It's not a terrible game by any means. There's no pay to win, though there is a cash shop. Progression is fairly slow, at least it seems that way so far. You'll mostly be murdering…”
