You move around in a 3-D environment, flip a couple of switches, open a few doors, travel through a warp or two, and shoot at enemies that are difficult to distinguish from background objects. Even the crosshairs are difficult to manipulate. What you basically end up with is a game that has you get right in front of opponents and blast them away... there's really no strategy or finess that you can use in combat, since control is poor and aiming is difficult. Once you've picked up all the data clusters in a level, you move on to another stage.
If I-War expanded upon, or even enhanced the genre established by Cybermorph, we could have dealt with it. But this game is inferior in both the graphics and gameplay department, with the only redeeming feature being a split-screen, two play battle mode that's dull and pointless. The puzzles, the mazes, the texture mapping, the gourad shading - none of this really gells together as a complete package. The five different perspectives on three different anti-virus craft aren't going to make up for that either.
