In Friday's MCV Industry magazine I received a one use only code to download an extra multiplayer map (called Dilapidation) for Lost Planet on the 360.
The map will only be available to those who preorder and codes should be shipping to retail shortly. Unfortunately I'm having teething problems with my Live account so rather than let it go to waste I thought someone else might make use of it if they're enjoying the demo.
To redeem go to Xbox Live Marketplace and select 'Redeem Prepaid Card'.
Please post when you have used the code, out of consideration for other members. Thanks.
