Strategy One: (Makes this level easy)
The key to this map is the play conservative with your vehicles. If someone can fly the Apache, then this map will be very easy. There isn't truly a base strategy for this map. Always play as engineers. If you take the Apache route, there should be two in the Apache. And two people in the tank. Keep these vehicles protected as much as you can. If your Apache starts to smoke, fly away! The Apache is very powerful against infantry units, but not that good against ground vehicles. Their purpose is to kill infantry and the helicopters that spawn. The tank is to take out other tanks and to take over the bases.

Strategy Two: (A little harder)
Have two people take the tank and two people be engineers with tracer darts. Have the tank take out enemies and the engineers take out any major vehicles like Helicopters and Tanks.

This one is quite short and one of the easiest ones to do. Many of the flags are near a building so you can stay inside the building while defending the flag to capture it. Engineers will be very helpful because there are a lot of enemy tanks, buggies, and enemy Heavy MG's.

First Flag - On the way to the first flag there is a Heavy MG. Once you reach the first flag, stick inside of it and defend the perimiter while you capture the flag. This one shouldn't be to difficult. If it is, have someone stay upstairs as they will be out of the line of fire.

Second Flag - The second flag has a Heavy MG on the roof and a tank that spawns in the area. Take care of the Heavy MG with a rocket and then have your engineers take out the Tank. Take cover in the building and do as you did previously, protect the perimeter and raise the flag.

Third Flag - On your way to the third flag stick to the right side. Have a engineer destroy the buggy with a rocket that appears in the center of the area on the road. Then follow the train cars up the right side to get into the building. Cover the building's doors and kill the enemies in the area. Some may need to be killed on the roof so that you can begin capturing the flag.

Will be using this thoroughly written guide Side

I'll add you. Do we need a full squad of 4 or is it possible with 2?

There can be as many as you want but on hardcore its really hard with just two people, lets try and get some more

[jackjackxattack]

Something i don't understand in this mode. Killing enemies take a lot of time which is not the case for my team mate. Somebody knows why ?

[Proudli]

Magnum ammo, also depends on the gun.

[AmbaLaBamba]

Thanks for the guide, thinking about purchasing this now because it's only 400 points.

[CGSDR]

Thanks for the guide, the DLC is great, more like the Halo Reach's firefight, but one thing that annoy me is, it's a peer host game, so for people who live in the edge of the world (NZ) is really hard to find a good connection server, that mean I CANNOT KILL ANY ENEMY (Sorry for Cap Letter), I can heal, resupply, be a spawn point for teammate, repair anything that has to do with my teammate is fine, BUT anything that same to do with the AI are all crap, and that happen on both side by that I mean If I join someone's game or I create my own and someone join me, and that "someone" cannot kill a thing. Is anyone having this problem too?

[Farley]

Just finished it, Good guide. Really the most important thing are using the vehicles the best you can. I would say the levels go in this order:
1.Desert
2.Isla
3.Nelson Bay
4.Valparaiso
