Some of you may not be old enough to remember ROCKET ARENA that began with QUAKE 1, and continued onto Quake 2 and 3, but this multiplayer mode was incredible! Not only was it fun being in a server watching 1vs1 or 2vs2 and waiting to get warped in for your turn in the round-robin tournament, but teamvsteam rocket arena was also amazing. Little would have to be done for this mode to work with Halo; ability to carry multiple weapons at once, including rocket launchers and a sniper rifle for starters, as well as zero damage from friendly explosives which can propel you with a well timed jump, as well as greatly reduced self-inflicted damage from your own explosives - namely rockets in order to use them for rocket jumping. What a great addition this game mode would be. I was unable to find any really good youtube videos that did justice and captured the feel of the mode but if you search it out you may find some.
I like this.
