1. Dual wieldable M6Ds. I remember me and my friend both opened up on this Elite with our M6Ds, he went down in seconds. Then I thought, what if we both had 2 pistols? Overpowered? Yes. Should it matter? No. 2. H1 and H2 PC Campaign Coop. Halo 1 is, in my opinion, the best game for coop. I've been playing H1 since I was 10, and it still hasn't gotten old. When HCEA came out, I was very excited for Coop. But there are just some things I can do on the PC that I can't do on the Xbox. So I'm still very disappointed. Did Bungie ever offer an explanation for why they didn't include Coop in H1 PC? 3. Catch, Thunderstorm, and Tilt in HCEA. I have an odd memory of my first time playing Halo 1 on Legendary. I remember Elites throwing grenades at me in the Pillar of Autumn(first level), don't know what that's all about, but I thought I could relive that memory, since 343i is including Skulls in HCEA... Nope. 4. Ugh... you guys continue the list. [Edited on 09.30.2012 1:02 PM PDT]
