Played this game a ton during the second week of it's release and I remember wishing the arcade mode had co-op or something where the second [maybe third and fourth] player could only move within the boundaries of first player and all could ride the same vehicles [bike not being accessible in this mode maybe?]. Quite possibly pushing it, but a splitscreen mode would also be nice if the players split like in Bionic Commando Rearmed.

The game has a fair number of bugbear issues that need to be resolved first such as the repeating sound glitch, the developer not knowing what a difficulty curve is, the fact that music volume doesn't stick when played through the jukebox, the fact that the game pulls several unexpected genre changes with little to no warning and the final boss battle has nothing to do with the mechanics you've learned the entire game.
