It looks like some very determined or lucky people managed to unlock the Custom game mode in the beta of Halo 3, allowing the players to use the Pistol and the Plasma Sword, and also a way to change the gravity. The movie system doesn't work well with these games though, so you'll have to survive with these fews images. Update: Lovas sent me a video that works long enough to see the Wraith tank in action, bugs included :) Update: The video showing the Wraith in action is now available.
Merci à AceParty pour les extraits.
