This game is based off the anime series MGS 0083 and has you taking the roll of the two sides, first as Zeon, then as the Federation. Control is done via the mouse, and is pretty standard for a SRPG, although it is worth noting quite a few weapons cannot be used after you've moved that round. The CG work is pretty good, although the animation and in-battle icons are pretty tiny and pixelized. There's a few additional details on the game over at this wiki
