If you notice Portal 2 updating today, don't be alarmed: it's only because you're getting the new Portal 2: Peer Review DLC for free. If you don't have a copy of Portal 2 to update, Valve have that covered as well: it's on sale for 50% off through the 6th.

Peer Review adds a new multiplayer test track for robo-buddies P-body and Atlas, and features a single-player and co-op Challenge mode.

Wednesday October 5. That will be the day in which the Portal 2 Peer Review DLC will be released. The free mission pack will extend Atlas and Peabody's co-op adventure and add a new challenge mode for single player and co-op maps.

Back when Valve announced first DLC pack, they also mentioned leaderboards so all your friends and a bunch of strangers will all know how exactly how smart you are (or aren't), which explains the 'Peer Review' handle. That means your performance will be graded by both Glados AND the conglomerate hivemind of the The Internet. NO PRESSURE.

In more 'free stuff from Valve' news, the third volume of the Portal 2 soundtrack, Songs to Test By, is available now on the Portal 2 site, featuring such classic hits as Some Assembly Required, Your Precious Moon and Robots FTW.
