343 Industries has announced the fourth Halo 4 expansion; Champions Bundle. With it, we'll get new maps, a new game type and 'more'..
To elaborate on 'more', what we actually get is:
· Bullseye Pack: Two new multiplayer maps, a sports-themed Spartan armour and a new competitive gravball game type called Ricochet
· Infinity Armour Pack: Set your Spartan up with impressive and legendary new armour
· Steel Skin Pack: Bring an elaborate steampunk style to your UNSC, Covenant, and Forerunner weapons
All three packs will be available to download separately, but it'll work out cheaper to get them all with the Champions Bundle.
