I've been absense for a VERY long time. I've might even be "in suspension for 99999...***". But here I am back! And not only I am back, no Portal 2 has got a new DLC:
The Perpetual Testing Initiative is online!
Portal 2 players are able to make their own testchambers now. BUT the new DLC has got a terrific new storyline as well!
You may not listen to the messages by Cave Johnson. But this is a mistake!
The new story is about parallel universes... (BLA BLA BLA) If you don't know: Watch this movie (http://store.steampowered.com/app/620/) and/or PLAY the game!
But anyhow, here is my suggestion for a contest:
Build testchambers, observation rooms, alternate Caves etc.
