Why not? Example: a black T-Shirt / or hoodie with the Yellow game case biohazard design on the front would be cool. Or the cool Killing Floor red graphic, or other Zombie design versions (of Zeds and players profiles) with cool tags like "Zombie Killer" etc. You could have a shot of West London and the strap line "I fought the Zeds and the Zeds won" (a ref to the Clash song of similar name). It's endless. Go on get 'em up in a KF Merch Steam store and ship to the UK.
