I haven't been able to get a hold of CtrlAltDestroy, so I'm going to be filling in on his behalf. CAD has a lot of experience with getting things in-game which were never intended for this engine. He's been extremely creative, instrumental, and artistic in what he's done. Here's some examples:
Halo 2 Sanctuary, all Halo 2 weapons, and Halo 3-like "backpack weapons"
Randomized melee animations (with the help of Kornman00's OpenSauce)
Zombie Mod, money/score tracking
Zombie mystery box
He's done a lot more, including things he hasn't even put into videos. I just wish he didn't go on hiatus until further notice. He pretty much abandoned all hope of another decent Halo game on the PC, so instead of holding his breath and wasting time, he just left.
Another member, ShadowSpartan, has a lot of experience with Halo's tag format and made a real-time tag editor to assist people in fine-tuning their maps:
Also, I just want to post something here to "show off" a mix of OpenSauce and a popular trend in high-end PC setups today...multi-screen gaming.
The preservation of the HUD's aspect ratio and FOV are possible thanks to OpenSauce.

On and off over the past few years I've also been working on a new Halo UI (makes use of features of OpenSauce):
In addition, I've worked with another member of this forum on a project to create custom gametypes for Halo servers. We created our own Zombie mod, similar to Infection from Halo 3 and Reach. We've also made another gametype called "Dogfight". In Dogfight, every player spawns in a banshee in the air, and they basically have to shoot down the other players. Players are unable to exit vehicles and rider ejection is disabled to prevent exiting from accidental flips. It can work on slayer, team slayer, and juggernaut, and with a few other hacks it could probably work on Race and KotH too.
