Valve is asking players to test Left 4 Dead 2‘s Cold Stream campaign. If 20,000 players finish it by Sunday, they’ll release the Dead Air campaign early! Coincidentally Left 4 Dead 2 is on sale for $US5 on Steam. [L4D.com]
Steam’s annual sale begins today and runs until July 10. These tend to be good – and you can also unlock achievements in games that can also net you prizes. Check it out! [Steam Store]
