You need team work to pull this off:
Offense:
1. After spawning rush to the cloak grab it and then jump down and get the grav lift. Deploy the lift underneath the spartan laser and go up top (There will most likely be an enemy up which will slow you down so just run right past him). After going up to the spartan laser jump off the opposite ledge and open the the gate.
As soon as you've opened the gate go into the building and go all the way around to the back of there base and camp (providing you don't get killed).
2. Two of your team mates need to be by the pipe on the right side of the map and one must have the rocket launcher. One if them goes into the pipe and heads to the room near the flag (stay crouched you noobs). While the other guy with the rockets goes up the ramp near the bridge over the gate and takes out any threat.
3. The other team mate was the one who grabbed the sniper and also got the bubble shield. He lays back and moves up to the gate once the other three have gotten the flag.
4. As soon as the rocket guy has killed at least one person the other two (guy camping at the back of the base and in the tube) move to the flag while the guy with the rockets covers. At this exact same time the sniper goes up to the gate and also covers since there's 3 other people still alive. By now there shouldn't be 3 people alive since the snipe and rockets is covering.
5. Run the flag right out the front door and as soon as the guy with the flag gets past the bunker the sniper drops the bubble shield behind him for more cover. All you have to do is run the flag back to the base and game over.
Defense:
1. Someone grabs the spartan laser and stays in that location to prevent anyone coming up from the grav lift. Watch out for there sniper though and be careful of grenades up there. The person with the laser must keep a very close eye on the flag as well.
2. At the start of the round two people get on a mongoose and go to the gate, get out walk around to the rockets and get them. Whoever gets the rockets go back inside the base and camp the flag at the energy drainer location.
3. The other guy must then attempt to get the enemy sniper, if you do get it head to the bunker and stay on top to spawn snipe the other team.
4. The last guy grabs the needler and a carbine and camps right beside the flag.
