Mission 11: Blackcats

1. The second vehicle mission of the game features Pvt. Miller operating the gun of a Black Cat airplane. Use LT to zoom and RT to fire. After a brief exchange of dialog, press X to switch to the turret on the bow.
2. Use this first run to attack the four Japanese PT boats protecting the larger merchant ships. Press RB to fire at them with the more powerful 20mm cannon. You'll make a brief run before switching back to the gun on the rear of the chopper.
3. Achievement: Your primary objective is to destroy 3 merchant ships that are trying to resupply the enemy. Before doing so, shoot the search lights on the front and back sides of each ship. Destroying all six lights will earn "Lights Out." You'll have plenty of time to do this, just don't destroy the ships before you knock out the lights.
4. You'll have a chance to attack two merchant ships and one PT boat in this run. Focus on the lights if you want the achievement, and make sure to destroy the PT boat when it passes.
5. Checkpoint Reached
6. After a brief run, you'll be knocked back by some enemy fire. Press X to get on the right turret.
7. Focus on the PT boats for the majority of this run. They're far away, making them hard to hit, so consider the run a success if you can destroy a few of them.
8. As another merchant ship passes, destroy the search lights. Then, press X to get on the left turret.
9. This run brings you close to a merchant ship and several PT boats. Destroy the ships first. If you haven't targeted the lights yet on the ships, now's the time. Otherwise, fire at the white fuel tanks towards the middle of the deck.
10. Press X to move back to the other side of the Black Cat. Again, shoot the lights of the merchant ship in front of you, then the fuel tanks.
11. Checkpoint Reached
12. Moving to the bow turret, you'll get one last pass at the merchant ships. If you're going for "Lights Out," use this opportunity to destroy any remaining searchlights. Otherwise, focus on pounding the ships with your weapons.
13. Strategy: It's possible to shoot both the regular machine gun and the 20mm at the same time. Just use two fingers to press the buttons.
14. You'll get one last chance on the left turret to finish off the ships. If you haven't done considerable damage by now, it's hopeless, and you'll continue the mission with a failed objective.
15. Checkpoint Reached
16. A distress call comes from a nearby U.S. fleet. The next objective is to fend off a squad of Japanese Zero airplanes.
17. Achievement: Destroying 45 Zeroes will earn "The Sum of All Zeros." This is an extremely difficult achievement that is best attempted on "Recruit" difficulty, as there will be fewer distractions. The best strategy here is to memorize where the Zeroes come from and be as efficient as possible on every run. Don't even bother rescuing survivors.
18. After an initial attack by the Zeroes, your accompanying plane, the Hammerhead, will fall, and your ship will land on the water to assist survivors of the Japanese attack.
19. Listen to your allies, who will call out directions of the attacks based on directions of a clock. Press X to switch to the right turret.
20. To make matters worse, a group of PT boats approaches. Take them down immediately, then press X to save a nearby survivor.
21. Continue to destroy PT boats while taking down as many Zeroes as possible. Keep an eye out for the prompt to rescue more survivors, then switch back to the left turret.
22. Strategy: Your gun moves slower when it's zoomed in. Let go of LT to get a better look at incoming planes, then zoom to take them out.
23. Checkpoint Reached
24. Keep gunning for PT boats as they appear, and shooting Zeroes when possible. There are two survivors to grab here before moving to the bow turret.
25. The Zeroes are your only focus on this last gunning point. Shoot as many as you can, paying close attention for those that fly right towards you. The mission ends when you run out of ammo.
