Halo 3: ODST made a huge splash today at E3, a ton of new footage was revealed. Now we learn that a new mode called Firefight will be included and it will feature 4 player co-op.
In Firefight, four players will fight waves of Covenant, kind of like Horde in Gears of War 2. Vehicles, leaderboards and skull modifiers will also be included in Firefight.
So basically this is like Halo + Horde with vehicles…..sounds awesome!
