I think there should be a Halo 4 CSI gametype, where two teams try to solve the mystery of a serial teamkiller who is randomly assigned to one of the two teams. You will need to investigate the weapons held by every character, and the sounds you heard prior to the death. Be sure to ask questions of witness, but be careful of leading them. Solve the murders first for points!
Invading world of the guilty as spirit of vengeance The guilty pay the price. I hate Square-Activision's FFXIII and its slew of cash-in spin-offs & sequels
