Star Wars: Battlefront II/Birth of the Rebellion

Capture the Radar Facility
This is a pretty large and confusing map, and believe it or not, avoiding getting lost is one of the factors that can determine success and failure. It starts out simple enough; you're in a hangar, and there's really only one way out. Climb up the stairs and go through the hallway. You'll come to a large circular area, with four paths leading to an enclosed, smaller circular area. That's the Radar Facility. As you can see, it's a pretty small room, so throw a couple grenades in to soften up the resistance (they can't really dodge the grenades) before moving in and finishing off the rest.

Retrieve the Holodisk from Command
There are three hallways leading out from the circular area; the one that you came through from the hangar, plus two others that lead to a small area (the "hospital bed" area from Episode III). When playing this map in Instant Action, you would take a right from here and continue on the corridor, because the path leading straight goes to a room above which serves no practical purpose; however, in this mission the Holodisk is located there.

When you get to the hospital bed, some Rebels will starting coming out to greet you. Again, use grenades liberally, as there are quite a few Wookiees here that could stand up to blasterfire for a while before going down (you might need to use the ammo droid located in the corner). When the area's clear, go upstairs and grab the disk; then get out of there before more Rebels spawn to kick your tail. Return to the Radar Facility to complete this objective.
