GunForce II

This game is so cool in how it uses vehicles since they create completely new ways on how to navigate the space on screen but also designed it so that you have a different means of traversal if you decide to go on foot. This creates a lot of new ways with how you interact with the space that enemies control which is further elevated by solid enemy design. I think the game doesn't do THAT much with on foot movement and some of the late game setpieces are lame, but pretty damn solid title.
