Digital Spy writes: "WarGames - the name for competitive multiplayer - contextualises one of Xbox 360's most popular past times by making it become a training simulator on board the Infinity spaceship. One of the confirmed modes, Infinity Slayer, is faster-paced than what we've seen in Halo previously but retains the treasured Halo fundamentals - from sandbox gameplay to fan-favourite weapons."
Default slayer and other gametypes will still have map power weapon spawns.
