The Gormgant boss is the most challenging part of the new Act 4 mission in Modern Warfare 3's MWZ. Bad Signal sees you delve into the Dark Aether Rift, a challenging mode centred around a spooky version of the Al Bagra Fortress island from Al Mazrah, where you have to break four seals by killing a tonne of zombies.
Once you're done, you'll have to escape the island, but before you can, Gormgant rears his big ugly head and starts trying to eat you. This is a very challenging boss, not least because you have to fight your way through the entire Bad Signal mission first before you can even attempt him. Still, there are some things you can do to make him a bit easier, most of which, sadly, involve prepwork beforehand. Here's how to defeat Gormgant in MWZ.
