Win signed Valve kit with Portal 2

Modders, on your marks; a new competition for Portal 2 has kicked off, asking players to think up the best single-player or co-op test chamber and then make it. It’s your chance to reinvent the portal, basically.

The contest runs until 11:59pm on June 6, so there’s not a whole lot of time to get creating. Winners will receive the Ultimate Portal 2 gift pack, signed by Valve (no portal gun included), as well as a spotlight on the developer’s website, showing off their creation. The best entries will be challenging but fun as well as sticking to Portal 2‘s crazy themes.

You can submit entries at, where there are more specific details on what creations must include.
