Strategy:
Your forces are located at the point 1. Infantry and vehicles send on cliffs and build up your camp there. You have two enemies. Evolved are located on the plane 2 and Survivors on the area 3. At the first, you must destroy their resources. Take a Grimm Reaper into a Transport Dome and send it to the point 4. You can destroy all Bull Ant Tanks here. (Hint: The enemy don't attack on the Grimm into Dome.) Then go to the point 5. Destroy all Oil Tankers here. After this, send your Grimm to the point 6. Attention on antiaircraft forces of Survivors! Destroy all Oil Tankers here too. Now, you can erase enemy camps. Combine attacks of Grimm Reapers with your Fighters.
