To the factory roof:

Follow this Battlefield 4 guide to navigate outside the destroyed wall, use your tactical visor, and reach the factory roof, dealing with enemy vehicles and choppers along the way.

Alright, so you've just blasted through that destroyed wall and stepped outside. Dunn's gonna hand you a cool tactical visor – think of it like super-powered binoculars that tag enemies, letting you see 'em even when they're hiding behind cover. Look north towards the big building and tag that extraction point. Now's a great time to use that 'engage' feature to have your squadmates go after the enemies up ahead. If you've got the M39 EMR, this is the perfect spot to try it out. You *could* try sneaking, but honestly, it's not worth the lower score you'll get. The area's pretty open, so using your new gear is definitely the way to go.

Keep an eye out, a friendly chopper will fly by soon and lend a hand. You can tell it to attack specific enemies you've tagged by hitting the RB button. Watch out, enemy vehicles are gonna start rolling in. Let your chopper buddy handle them and clear the path. Follow the road, but be ready for another group of enemies waiting further down. You'll see a big explosion up ahead – just walk past that area and take out the next wave of enemies. Make sure you use your grenade launchers to blow up those trucks on the bridge. Once that area's clear, head under the bridge and go past the pipe.

After you're out of the pipe, stick to the right walkway. Your chopper's gonna have to leave because of some RPG fire, so you're on your own for a bit. Keep taking out enemies as you go, and use the cover on the walkway to deal with the guys below. Once the front of the factory is secure, follow your squad to an elevator. It'll kick on as soon as you hop in. While you're going up, get ready – a chopper's gonna attack you. Once you're out of the elevator, stick close to your squad to avoid that chopper's fire. They'll lead you straight to the extraction point.
