They canceled Fusion Fall because there were too much bugs and glitches in the game. The creators were having difficulty making money off of this, and the financial rates were going down. If I'm correct, they might make a new one with no bugs or glitches. If there were bugs or glitches, they will probably be minor ones (ones they can fix.) If there are major glitches... well, that's just sad.
They have made a new game but don't play it it is so bad i doubt anyone would even rate like once it's graphics are horrible and game play even worse because the main thing to do is spam and that's about it
