Arma 3 will go Steam-exclusive, with the development team at Bohemia Interactive stating the move will ensure a 2013 launch.
"We have evaluated the pros and cons, but in the end Steam enables us to release Arma 3, brings massive advantages to the game, and improves the end-user experience. Not to forget, the majority of our players already come from Steam," said Bohemia Interactive CEO Marek Španěl.
Bohemia is also exploring more Steamworks integration to "enable game features that are impossible to develop in-house, on time." Further details will be announced later, but the intention is to provide access to user-generated content and multiplayer.
