i was playing skyhammer on underground. i was standing on the platform of teh 2nd objective, and i threw an airstrike to the right (when looking at the attacker spawn point, near the door that leads to the barricade generator room), that area actually got aistriked, and you could see the light of explosions following the grenade trail. my cooldown also was 1:15 instead of 0:25.
i read in the last update that indoor airstriking was disabled, but it still works. (at least in this spot)
