As the title says, Valve is releasing some free Portal 2 downloadable content tomorrow for all three versions of the game. The pack includes additional co-op levels, a "challenge" mode for both the singler-player and multi-player games, as well as the addition of online leaderboards, which in my opinion are basically useless since a few thousand metagamers obsess over the game and make it impossible for anyone else to even dream of getting to the top. Anyway, I'm still looking forward to the extra levels and can't wait to play them with a couple friends.
P.S. Still planning on doing a review or something on Catherine and From Dust this week, just haven't gotten around to it yet.
