Easily one of the most creative and distinctive fights in Icecrown Citadel, the Gunship Battle is something many raiders have been looking forward to since BlizzCon 2009. As a little bonus, this fight is also the source of a certain cloak that's white and longer than your average cloak.
Here's the basic story. As you've just managed to lay waste to Lady Deathwhisper, you ride the elevator up to where you'll see the Horde and Alliance doing battle. The fight happens almost identically the same whether you're Horde or Alliance. The only difference is which faction leader you're attacking and which faction leader you're following.
You pick fights with small parties of the enemy faction as you fight your way to get to your gunship. This is the same ship that's been circling Icecrown for all of Wrath, so you'll probably recognize Orgrim's Hammer and Skybreaker. You'll want to be sure to grab a jetpack as soon as you get onboard, and spend a little time shooting around and getting used to the rocket jump. Even if you're not going to be part of the raiding party attacking the enemy ship, the jetpacks are too much fun to completely ignore. Also, as has been mentioned before, these jetpacks gave rise to the infamous Rocket Bear.
Once the encounter starts in earnest, you'll quickly find yourself fighting the enemy in ship-to-ship combat. Let's take a look behind the jump and talk about how this is going to work.
