Unfortunately, Retro Revengers is only half a game. You play the first 5 stages with a specific character each, and then you start over, but with all 5 characters available to switch to mid stage. Along with the boss rush at the end, you fight all 5 bosses 3 times each with no alterations, and they're not very complex to begin with. At least the final boss is pretty fun.

The 5 different characters are a neat feature, but not all of them are useful in most situations, and there's one I'd say is completely worthless. All in all, Retro Revengers is decently fun, but completely skippable
