Well H: CEA (Combat Evolved Anniversary) multiplayer isn't bad.
Pros:
- no armor-abilities
- sightly faster Spartan
- sightly increased jump height
- zoom pistol
- maps are glorious. Hang 'em High = 2001 flashback.

Neutral:
- Love it or hate it, pistol is king. 3 shots to the head and you're done.

Cons:
- Pistol makes every other gun useless.
- Melee system is fucked.
--- Melee + pistol = no kill.
--- Pistol + Melee + Pistol = no kill.
--- Pistol + Pistol + Pistol = death
