Men dressed as Halo 4 characters Master Chief and a commando helped to create hype for Monday’s release of the video game by patrolling near the Game store in Bury St Edmunds.
Zombies and other military characters are expected to make an appearance for Monday’s release of Call of Duty: Black Ops 2.
Starbucks will be open from 10pm and gaming company 360-bse will be supplying televisions and Xbox 360 consoles to enable visitors to the Buttermarket coffee shop the chance to play the game for two hours before its official midnight release.
More than 440 people have already paid deposits for Call of Duty: Black Ops 2 at Bury’s Game store.
Christopher Smith, owner of 360-bse, said: “It should be a fun night.”
