Hi All
Have not seen this posted so figured I would mention it;
Left 4 Dead 2 (Low Violence Version) is on sale on Steam for US$4.99 for the next 33:41:34.
This version features toned down violence due to Australia's lack of a R18+ rating at this time.

(MODS: This is not related to Steam Summer Sale, so have linked via google, let me know if this is not allowed)
It would be worth mentioning that some people have suggested getting a US friend to gift the game may be a different version…
