Marseille77, after many addons, has released his first mission for Arma 2 in the BI forums.

Quote Marseille77 :
Today I present you my first mission made for ArmA 2. This mission was a reproduction of the OFP editor manual example of the original 2001's installation. As an russian sniper you have to kill a troop by the americans and have to protect your uaz. The place of origin was Island of Everon at the village of Entre Deux.
