The last map on IS Defense is the Croatian Mainland sets in an Airport Runway, so far this is the hardest map on IS Defense the enemies spawn in every angle, many infantry are scattered on the area and vehicles reenforcement are very fast.
The goal to complete this map is you have to kill 4000 Terrorists and 300 Vehicles.
Even though we unlocked the no-reload skills the best time we only get is at 2:00 minutes.
