froggyluv has released SP mission for ArmA2 in the BI forums.

Quote froggyluv :
"Chernarus has been sitting on an uneasy 9 month cease fire between Nato and Soviet forces. More dangerous still, are the soldiers left sitting idle without purpose. Still recovering from a macabre house party, you are sent to serve under the notoriously unscrupulous Captain Anderson."

-SP story driven mission rather than objectives.

-I most highly urge you only to play this in VETERAN MODE! Waypoints may be wonky in Cadet and all of those saves and enemy radar screens will probably break missions if not immersion.
