Sony has now confirmed that the PlayStation Vita entry into the Killzone franchise, Killzone: Mercenary will launch on 18th September in Europe, so we assume the local launch too.
The campaign is said to clock in around nine hours and follows the events of the original console Killzone. Interestingly though, the story will inter-tangle moments from the entire series.
Mercanary will also feature an eight-man multiplayer mode.
Sony has released this new trailer marking the announcement.
