I live for Halo 2's BTB.
And customs... but mainly BTB.
I see tons of people getting excited for Halo 2 BTB. I must admit, Halo 2 BTB was my favorite of the Halo games. Coag, Containment, Relic, Terminal, Zanzibar, etc... With that said, I'm actually more excited, to be able to get into lag free games of CE BTB. Playing against XB1 controller players and not mouse and keyboard kids, is going to be amazing. Sidewinder, Blood Gulch(I don't really like BG to be honest), Danger Canyon, Gephyrophobia, Timberland, Infinity, etc.... It's going to be amazing.
I'm still really excited for some Halo 2 BTB. 1 sided OBJ on Relic, Gulch Wars on Coag, Neutral Flag on Waterworks, 2 flag on Containment, assault on Zanzibar, even BTB territories on Terminal is amazing.
This collection can't come soon enough.... BTB is back.... :.)
