As announced last week, Portal 2‘s free Peer Review DLC is now out. What was not announced before though is the price cut on the game itself that’s now in effect on Steam; grab the game now and you’ll save 50 percent on the price Valve already permanently lowered some time ago.
You’ll have to hurry though, the price will be back to normal tomorrow.
Here’s the official word on what’s included in the free DLC: “Peer Review is the first DLC for Portal 2, the year’s most brain-bending action-adventure game. Featuring a devious new co-op track that continues the story of Atlas, P-Body and GLaDOS, the DLC also includes both single and multiplayer challenge modes, plus leaderboards so you can compare your portal placement and time scores with the Portal community.”
