Sony have sent me a free 'character skin voucher' code as a gift for downloading the demo, apparently...
I have no plans to buy the game, so this code is useless to me. If anybody wants the code, reply here or PM me and i'll pass it on. First in best dressed.
I can only assume that this code isn't hard wired to the PSN account that downloaded the demo, so it should be fine for anyone to use.
If someone knows otherwise, please inform me!
