Rusty as fuck, but playing some MCC mods has been an interesting experience so far.
>Trooper Firefight
Lots of cool ideas, but way too much of a clusterfuck. No weapon hud icons kinda makes it iffy to know what's what, especially in the first person demo, and slowing the player down on damage is kinda super shit since even a scratch dogpiles into a death. Makes me wonder how Halo with a SOCOM playstyle over top the player's head would play.
>Sierra 117 Nighttime (H3 on ODST)
Was very interesting at first, if buggy with the bloom being blown out on anything glowing when VISR was on, but then the dev throws an absolute clusterfuck later in the mission and.. AUG rifles? Feels like a test bed of shit thrown at a wall, not sure if I wanna try the others.
>Second Strike
Fun, if a bit awkward on navigation of empty spaces at times and I think I skipped an AA turret somehow. Nice CE-in-2 feel to it.

What are your favorite mods?
