Apart from this being a boring game with controls so bad that it causes dizziness, I don't recommend this game because of the behaviour of the developers themselves.

Because of its low User Score on Metacritic (4.7 out of 10), the devs made an official announcement where they asked gamers to spam-vote perfect 10s in order to manipulate the result, while at the same time calling those who gave them low reviews "♥♥♥♥♥s" and "trolls", among other insults. When I and a few others remarked on how unprofessional that was, we had our comments and posts deleted, as well as our names included in a very public "Hall of Shame" (which was also deleted a few days later) where the developers attempted to ridicule and humiliate us as "trolls".

When almost no one posted any favourable user reviews on Metacritic, they asked Steam to remove their Metacritic score from the game's store page, as it gave them bad publicity (and that's why it's no longer here), but not before one of the developers (called Alexander "motorsep" Zubov) posted a fake review, giving his own game a 9 out of 10.

Companies that behave this way don't deserve any business.

This game is awful. The camera is so poorly designed that it is the only game I have ever played that made me feel sick; my friend and I couldn't even last 20 minutes of gameplay time without feeling nauseous. Save your money and skip over this one.

Controls are weird and floaty but tolerable. Combat is fun, definitely the strongest point of the game, but there isn't nearly enough of it. Most of the time you wander around levels looking for keys and switches wondering why there's nothing to shoot at. Enemy shots are often the same color as the ground, so it's hard to see them coming at you. Don't bother.

The game is mediocre at best; horrendous controls/camera married to utterly average content.
What takes this from 'blah' to (a more enthusiastic vomit noise) is the complete lack of integrity on the part of the developers. Do /not/ give these people money.

Very fun singleplayer & multiplayer experience. I got this game through the Humble Bundle and it was one of the first games I could run on Linux. Consider grabbing it if you like arcade games that involve shooting at enemy ships with an overhead perspective.
