A freeplay-sandbox map pack with 32 maps from all three S.T.A.L.K.E.R. games (and one map made from scratch) with a-life on over 400 smart terrains. There is no story but there are about a dozen repeatable tasks available throughout the Zone. The mod is featured as a modding resource but can still be played on it's own.
Testing a heavily modified SoC heli_combat.script altered to select it's own targets dynamically instead of predefined targets through custom logic. I modified my stalker scripted combat planner to target helicopters. It works pretty good after only slight tweaking.
This scenario is set up only for testing purposes. Under normal circumstances we won't have military attack everything in sight. Helicopters will only engage trespassers and stalkers who engage in combat with military squads.
There is a shit ton of work to do for helicopters left, but this a big step up. Helicopters will add a lot of expansion to gameplay.
