Nice game mode...That reminds me of a game called Crossfire,it has this game mode where the same thing happens in the game mode virus..Each round has 8 minutes,when the round starts,it gives the players 20 seconds to run and hide,when the 20 seconds run out,BAM the game chooses randomly any player to be the mutant.If the mutants dont catch all the humans when the 8 minute round is over,the humans win. If the mutants do catch all the humans before times up,mutants win,
Nice Idea...
