Halo 4 is set to mix up the acclaimed shooter franchise's multiplayer system with the introduction of a raft of perks and customisation options.
Showing off the forthcoming Xbox 360 blockbuster at Microsoft's Xbox Showcase, developer 343 Industries revealed that the game will allow players to personalise every element of their Spartan warrior's appearance, which will have an impact on gameplay.
The introduction of a perks system, which will see gamers evolving their online characters and capabilities as they progress, is reminiscent of similar features in the popular Call of Duty and Battlefield games.
However, franchise development director Frank O'Connor reassured long-time fans that the core Halo identity will not be compromised by the new additions, only developed.
Halo 4 is due out later this year and is the first brand new Halo game to be developed by 343 Industries, following the departure of series creator Bungie.
The game will continue the story of iconic hero Master Chief and is designed as the launching point for an all-new Halo trilogy.
