but I dont get it, how can you do COD + sandbox MP ?
You just have both
Like in Unreal Tournament 2004 you had your standard fast paced deathmatch and CTF, but you also had giant onslaught/assault maps with vehicles and stuff
Pff, then its not COD.
C2 already made a difference because of its map desing (COD: running around a flat cube full of holes and tunnels, while C2 had paths and more dynamic maps/desing)
But fast paced =/= COD :/
