Vectorman, Rayman, Megaman, I tell ya, as long as it's got man in the title it's bound to be a good 2D platformer... Anyway, Vectorman doesn't have any specific concept or gimmick that the game is based around, it's just a well designed 2D platformer shooter with some cool boss battles. There is a good range of environments, and a really nice mix of vertical and horizontal gameplay. The controls are simple to understand, but difficult to master, and the level design is sure to require the player to exercise both platforming and shooting skills in interesting ways.
