A PC version of Sniper Elite V2 is also in the works, which will be self-published by Rebellion. Reps for the game tell Joystiq a demo for the PC is also planned for "sometime next month."
There's no telling what the demo will include, but Joystiq's recent preview should give you a good idea of what's in store. Sniper Elite V2 -- and its Kill Hitler pre-order bonus -- launches on the PC, Xbox 360, and PlayStation 3 on May 4.
When asked if the bonus would be made available as premium DLC in the future, a rep told Joystiq the developer has yet to determine the content's fate following launch. Our guess is Rebellion will give everyone a shot at the world's most hated man at some point -- it's just a question of cost.
