While I was wandering the void that is the Internet, I came across these cheats for Gundam vs. Gundam: Next Plus. Sure, the game came out a while back, but the game is worth trying, and these cheats make it more interesting. Here are some cheats that allow you to play as the game's bosses, shrink your Mobile Suits, play as custom fan-made units, and so much more.
