It really is a damn great game for a small price!

I even have to say I have only learned through PlayStation Plus.
Have it downloaded free and must say it is amazing. Had I not been there, I would buy it immediately.
The graphics are really more than beautiful, just stunning.
There are really a number of enemies, and also "your / my 'spaceship is extremely horny.
Sorry but there are only 3 spaceships, but all three are completely different, the handling, weapons and so do the properties have "sub-properties". There are currently only 5 or 6 level, by design, are all different.

This game is perfect for in-between! Via "Remout Play" on the PlayStation Vita however, it is unbeatable! It is not boring and is perfect if you just do not have much time or just to relax so!
A strong buy recommendation! (A repeated action of PlayStation Plus for this game, I would not wait!)
