The Australian version of Left 4 Dead 2 has been very strongly censored. No gore, limited splatter effects, no decapitation and zombies bodies vanish very quickly after being killed. Uncommon infected also do not spawn in the Australian version of Left 4 Dead 2, anybody joining Australian servers will not see any Uncommon Infected (eg Riot Police) during the game. The changes make the game much tamer than the original Left 4 Dead released last year.
