This level is the grittiest, nastiest, most in-your-face level of Battlefront. The map is small, and except for the few units that fly aircraft, everyone is fighting in one place. This is where you can show your mettle and prove that you can beat the game. You can't escape the hack-and-sack point-blank fighting on this level, which is why it's a favorite of many players.
Move quickly when you start this level: spawn as a grunt soldier at your forward command post (3). Run to CP 4 and hold off the opposition that's also trying to take it; if you get there quickly enough, they shouldn't be a problem. Once you have captured the neutral CP, make sure there are no enemy units on that platform, and move to top of the corridor. There will be a ton of enemies pouring in the other end of the "hallway": throw at least one grenade to slow them down and just start firing at somebody in a stormtrooper outfit. The main thing to watch out for in this section is enemy grenades. Just keep gunning down enemies from the middle of the corridor until you feel the momentum of the battle swinging your way (a good indicator is your allies moving up to the platform). Be careful to not get within range of the anti-aircraft gun sitting atop the tower; it works just as well on infantry. As you move out of the corridor, look both ways to ensure that you won't get pounded from behind when you turn to take out a few units. You can also hop into a friendly starfighter and fly to a CP behind enemy lines to cut off the flow of reinforcements to the main battle, although if your'e shot down, you will be at a disadvantage in the fighting that follows. Your soldiers will often be too stupid to hold CP 4 in your absence.
There's a certain rhythm to this type of fighting. Once you feel that pulse, the rise and fall of the battle, the gut instinct to lob a grenade around a corner - then you are using this incredible new gameplay style to its full potential. With practice, it is possible to rack up more than 100 kills on this level, using nothing but a blaster rifle and grenades.
