4. Resogun
Resogun is a size scrolling space shooter where the levels all rotate like a globe as you scroll right and left. Your goal is to shoot all sorts of alien technology while simultaneously focusing on rescuing survivors. The easiest game to compare it too would be Super Stardust HD, primarily because Resogun is made by those same developers. It obviously isnt anything story intrusive but it is an addicting game to actually play. One of the biggest reasons is just how bright and epileptic the color palette is, creating a game that is artistically breathtaking. It is also another free title for Playstation + members so enter that voucher and try it out!
