For me, Halo ODST firefight was the epitome of competitive cooperative play. I have introduced many friends and family to Halo through the ODST firefight because it isn't the cut-throat competitiveness of online multiplayer. Unlike Reach's firefight where the point was to steal your teammate's kills, ODST was about lasting as long as you can against ever more difficult waves of enemies. ODST firefight may have had mindless gameplay, but I have never experienced more teamwork and camaraderie in any game mode in any game before or after. Gears 3 horde, Reach firefight, COD zombies , etc was about beating your teammate where ODST was about working together to last as long as possible. I cracked 2 million points only once and I loved the thrill of hero'ing someone back from death at the end of a wave. All that being said, I have a few suggestions for 343i.
Please please PLEASE bring back ODST style firefight! Endless increasingly difficult waves of enemies. (Covenant, Flood, Human, and Prometheans)
Forge firefight. Build your own firefight map. Enemy spawn points. Recreate Halo or IRL battles. This would deff get me into Forge!
Storytelling through firefight. Story can be progressed through hints on the level. Let the player learn a story through exploration.
Lastly, Horde mode style defense. Auto turrets, walls, mines, sentries, etc. Give us the tower defense FPS we always dreamed of.
Vehicles and large maps to use them.
So, what do you guys think? Push this through to 343i and let our voices be heard!
