I've got a preview build of the in-limbo PS2 version, and it's pretty bland. RoboCop moves too slowly for a FPS, and the only way to compensate for that would be to really go overboard on the destruction, letting you blast the crap out of everything. But they don't. You trudge around and shoot bad guys. Scenery is non-interactive and boxy, levels are uninspired.
Stomp...stomp...stomp...target...blam...stomp...st omp...
Play the Exoskeleton level of Red Faction II instead. Much better.
