Bundling download codes for extra content in pristine boxed copies of games is trendy - even Disney's doing it.
Tron: Evolution will gift extra multiplayer maps and skins to anyone who buys the game legitimately, new, from a shop. It's meant to discourage second-hand sales.
The extra maps - Codestream Nexus and User's Plaza - will take the game's multiplayer total to six.
Tron: Evolution, a movie tie-in, is due out on Friday. Turok remaker Propaganda Games is behind the project.
The film it accompanies, Tron: Legacy, will arrive in cinemas on 17th December.
