In this mission, you have to destroy nine ships and shoot down one of four planes. Use caution when locking onto the ships as they launch missiles at you like crazy, unlike the ships in the previous mission which only fired bullets at you. Aside from that, completing this mission is fairly simple. It ends when all target enemies are destroyed/shot down.
- Destroy/Shoot down all targets.
The reward for this mission is 30,000 credits plus a minimum amount of 101,000 credits. More credits can be earned from shooting down the enemy planes with bullets. The A-10 Thunderbolt II and the F-4E Phantom II are unlocked for 200,000 credits and 170,000 credits respectively. The next mission, Through the Valley of Death is also unlocked.
There has been a report from some fishing boats in the area. It seems there is an unidentified fleet converging on the Castalia Sea. Contact has since been lost with the boats, leading us to believe it is a United Forces fleet. You must find the fleet and annihilate it. Over and out.
Delta Leader: (When mission is selected on the map) A United Forces fleet has been detected. The mission is to attack the United Forces fleet. Show us what you've got.
