A Halo modding community has accidentally made various hidden game files public, found by retrieving hidden data in the Halo 3 Beta code.
Before we go any further, a warning: the following are in no way official or confirmed features of Halo 3.
* New equipment: Instacover ; Smoke (suggested this might be a smoke grenade?) ; Jammer
* New vehicles: Chopper ; Pelican ; Shadow
* New weapons: Flamethrower ; Claymore Grenade
* New mode: Infection (described as "Destroy the Flood or become infected. Score points for killing flood or big points for infecting a human. The player with the most points wins."
* New rankings: The highest rankings are now Killpocalypse and Killionaire, instead of Double Kill and Triple Kill.
* A reference to a map editor has also been found, a returning feature from Halo 2.
