Get stuck into the Potato Sack now.
Want to unlock Portal 2 on Steam ahead of its published 22nd April launch date? Then you’d better get stuck into the Potato Sack indie bundle.
The Valve countdown clock reported earlier today has hit zero, revealing a new page stating “Portal 2 Steam systems offline. Computing power required for launch.”
To force an early release it seems you’ll have to go and play the various Potato Sack titles until a “computation” bar has filled up.
