Wasteland Kings, by Vlambeer, is the precursor to Nuclear Throne which is a game that’s available for purchase via PSN. This game is a top-down shooter in which you fight enemies in a nuclear wasteland in order to become its ruler. Wasteland Kings sounds like a pretty odd game but it’s actually a lot of fun! (Game running on the PSVita)
This game includes:
A couple of different weapons including a shotgun, grenade launcher, pistol, crossbow and melee weapon
A leveling system in which you gain EXP by collecting radiation from fallen enemies.
When you go up a level, you can pick a mutation to make your character better (similar to Borderlands 2)
The ability to choose between 5 different races which all have all have different mutations you can choose when leveling up
The framerate of this game port sometimes goes down a bit but it’s still good enough to be enjoyable. Sadly, this game was buried under other stuff as its Reddit thread was deleted so the only link provided is its download link.
