Portal 2 Challenge Mode DLC Is Coming Mid-September
Valve promised Portal 2 DLC to come sometime in summer but with the season coming to an end shortly, it’s hard not to wonder if they will be able to keep their promise. Valve is famous for delaying things – and it wasn’t a surprise when Valve’s marketing VP, Doug Lombardi said – it will be out in mid-September and pointing out that mid-September is ‘still technically summer’.
When Valve first announced it, they mentioned new test chambers with accompanying leaderboard and a challenge mode playable either singleplayer or coop and that it would be free on PC, Xbox 360, and Playstation 3.
