IMPACT! should have been a multiplayer and expanded version of G. Too bad life sometimes gets complicated. And this project was aborted.
The game should have featured team battles, several multiplayer game modes, different starships, devastating super-move abilities, multiple arenas, powerups and a faster gameplay.
A multiplayer game will come, just not this one. There are too many G like games already.
