The standard things, Flood, Forerunner vehicles, offline Spartan Ops, dual-wielding, brutes. Not the drones though... dear god not the drones. The Watchers are bad enough, and they at least fly away when you shoot them. Those things were some unholy watcher/crawler hybrid, but also Needlers. I'd love to see our little Huragok buddies return, they're one of my favourite things. New weapons, of course. Something to make the Forerunner weapons a bit more distinct. I was thinking something to do with the ammunition, but since there's already cooldown and clips, I wasn't entirely sure what it would be. Some other kind of flying machine for multiplayer. We've got the Banshee, the Banshee, the Banshee, and the Mongoose off a ramp/cannon. I'd like to replace two instances of Banshee in that last statement. A new variety of Forerunner enemy, be it mechanical like the Sentinels, or Promethean. As horrible as it would be, they lack a "Hunter", so something big and bulky that eats ammunition for breakfast, lunch and dinner. To make it different, have it use a more spray-and-pray type weapon as opposed to the one-shot kaboom of the Hunter. And finally, another Halo. Or two. Or all of them.

With regards to Lil Dog's comment about brutes and drones, they didn't have their entire species on High Charity. Brutes occupy vast stretches of space just like many other species in the Covenant, and I'd say something similar with regards to drones, but I'm not actually certain. I'd love to set the game to easy and try to punch down hoards of brutes like in the good ol' days! Most of those ideas are fantastic, and a few would be fairly easy to implement. Some of the new things, reptilian beast, mini-scarab, (The Locust's kinda like that) and since they aren't in the game, brutes and drones, would take a fair bit of effort to use. They've got a sorta-flood, but I'd like to see it more bloaty and infected again. The Pelican mission is an amazing idea, especially since it's already designed for three people to be able to use it. And it's in the game already! Just stick a turret in the back or something for the fourth guy. Broadswords would be interesting until your teammate decides to knock you into a wall and send you both to fiery oblivion. I like the alternate objectives as well, keeping Majestic alive instead of a bunch of scientists sounds much easier. The bomb arming would probably end up like the chapter where you disarm all the Havoks, except in reverse. With regards to the MAC, they could always bring back the Mammoth. It's got vehicles, turrets, the MAC, of course, and enough weapons to keep four people stocked for a whole chapter. Defense, assault, whatever. First person to the targeter gets to fire it! The Flood missions are really easy as far as story goes, there are Flood on Halos, there are containment procedures, there are idiots to release Flood. It writes itself. Again, I'd like to see them bloatier and more infected. As a final thought, I'd like to see some in-game mention of the Precursors. Nothing major, just tidbits. Maybe a mission where you find a not-quite Forerunner artifact or something.
