It is just a fantastic Game. I recommend you turn on ALL visual effects to enjoy this. Looking at the other reviews 1-2 hours on record of gameplay isn't enough to truly expereince this game. Round 12 + Is where people need to really review this game. If you want fast paced? This is it. Overall the controls are hard to get used to sure but for me a keyboard and mouse are absolutely fine. Once your past the learning cuve this game is a blast. Literally.
The ships look truly stunning flying past then with their cannons balsting the enemy fighters. And once you are in the higher round and the cruisers are fighting each other its becomes really fast paced. And you can choose to start at round 19 once you reach it and go from there to "Infinity". So it does give you the option to bypass the slower levels once you clear them.
All in All this game is a 10/10 for me. If you want a High paced Space shooter then this is for you. Graphically stunning and great game play.
Cons? Honestly if this had muliplayer I'd be on 300+ hours by now. Its a shame they never gave it the ability for online.
