Mission 15 - Operation Giant’s Step
Russel Faulkner “SERPENT” (SU-37 Terminator)
Keep destroying targets as fast as you can until you get +5,000 points above the quota. SERPENT will appear as soon as you do this, from the southeast along with reinforcements. To save time, destroy the air targets in the eastern side of the mainland, the ground targets to the west, before finally moving to the fleet to the southwest. This should allow you to accumulate more than enough points to trigger this ace's appearance, which will be conveniently near the enemy fleet.
