Valve has announced that its newly-released puzzler Portal 2 will receive free downloadable content in the months ahead.

Called DLC #1, the pack will include new test chambers, leaderboards, a challenge mode for both singleplayer and multiplayer, “and more.”

The DLC will be free on all platforms.

Gameplanet had very high praise for Portal 2, writing, “Portal 2 manages to exceed expectations without compromising any of the core gameplay that made the original so popular, and should easily be considered one of the best titles available so far this year.”
