Valve will offer early access to the Left 4 Dead 2 demo tomorrow to anybody who has pre-ordered the game on Steam.
If you fit the bill you can begin pre-loading the sampler now. If you don't, you can wait for the open demo-for-all on 3rd November.
Gold Xbox Live members can enjoy that taster on the same day (3rd November). Silver subscribers, on the other hand, need to wait until 10th November.
Left 4 Dead 2 launches proper on Steam from 17th November. Shops will stock the PC and Xbox 360 game from 20th November.
Those of you attending the Eurogamer Expo this week (sold out, sorry) will have even earlier access to the Xbox 360 demo, which will be set-up in LAN multiplayer for your amusement. Show begins tomorrow in Leeds and arrives in London at the weekend.
I'll be the one with "Bertie" on my back and hair on my face. Say hi!
