There are a few things I'd like to see in Halo 4 (Specifically Multiplayer).
First of all, I'd like to see the ODST Magnum make a return. I mean, it had a great look that made me feel like a stealthy bada$$. The power could be a bit better, considering it does fire a .500 Magnum Round. Next, I'd like to see some stealth integrated into gameplay. The silenced weapons (Bring them back!) could have a great impact on this type of gameplay. At least put stealth gametype in Matchmaking. Also, I saw your 5-second motion capture sequence in the VidDoc and it made me think, "PARKOUR GAMEPLAY!!!!!!" I would love to have a "Runner" where, like Juggernaut, a player is singled out the rest of the players. The runner has to get a package to the designated delivery site, usually across the map, without being killed. You kill the runner, you become the runner. I mean, C'mon, Put those Spartan Augments to Use!!! Armor could have an impact how fast your character moves, as well as their strength and health. Oh, and the runner has an M6/SOCOM that does 200% Damage! Just some ideas. Do u like em?
