imo... Zombies is just another gametype, it was introduced in Halo in later titles, Halo 2 i think it started but def Halo 3 but the point is.. as one of you guys stated earlier its pretty much everyone's gametype.. im sure ZA has specialised rules for it and another clan we're allied with also does zombies but they do it differently .e.g. camo makes all zombies invisible, humans cant pick it up and overshields freezes all humans.. Thus ZA zombies is different from CnR zombies and so fourth... ultimately its up to the players which variant is their favourite... I dont need to say which one is the most popular
