Activision is to launch the World's first over 18's live outdoor ad for Prototype 2.

The ad, which recreates scenes from the upcoming release, includes bloody battles between James Heller and his nemesis Alex Mercer, and is suitable for a post-watershed audience only. 

The ad will be shown in London's Covent Garden at 9.00pm on Sunday 22nd April, or for those unable to attend, will be streamed live on the Prototype 2 Facebook page.

Fans will have the opportunity to vote for one of two endings from 20th April. The ending that receives the most votes will feature as part of the grand finale of the advertisement.

According to Activision, "the game has been rated by PEGI as 18. This live action advertisement reflects the game in its hard-hitting, fantasy nature and whilst we’re excited to bring this new game to our legions of fans, it would be inappropriate for under 18s to view it”.

The Teaser trailer, which you can see here, starts with Heller leaping off a skyscraper and crashing into the street below, then dusting off and getting into a giant blade-off with Mercer. Expect very bloody hell to be raised.

Prototype 2 will be available on X Box 360 and PS3 from 24th April and PC from 24th July.
