The composer of Still Alive, the infectious ditty that closed out Portal, has written a new tune for the impending sequel.
Songwriter Jonathan Coulton confirmed its existence with the following tease on his Twitter feed: "Closing the doors. If this plane goes down, the Portal 2 song goes with it. It is in my pocket..."
No further news regarding in what capacity the tune will feature, but you won't have to wait too long to find out. Valve's much anticipated sequel to its 2007 puzzler drops out of the ceiling on 22nd April.
Check out the spoilerific clip below to remind yourself of Coulton's original effort.
