Turn to your right and touch the left and center control panels to disable the force field and open the left hangar door. Now, return back to the hangar and enter the left hangar door. There will be another Skaarj here as well as an ASMD Core and Med Kits here.
At the end of the hallway, take the lift down and challenge the next Skaarj guard. In the center of the room is a large machine with a control panel. Touch the panel to disable the rear entrance force field controls. Then, touch the control panel along the outer wall to open the next door. There will be another Skaarj in here with a Flak Cannon. When he falls, collect the Cannon and continue through the hallway to go back outside.
When you get outdoors, turn right and be ready to face a small number of Skaarj and Krall. Fortunately, you'll also see lots of Nali Healing Fruit around. Keep moving along the right side until you reach the entrance to the church. There is a bug here that sometimes stops the doors from opening. To reset the door, walk down the front stairs and back up.
Inside the church, walk into the first room and take on the two Krall by the statue. When they are dead, enter the door on the right side of the statue until you reach the control room. There is a Krall Elite working here. When the room is clear, check the computer to learn:
"No unauthorized access to lower church catacombs. All personnel must be checked by security before access is granted."
Then touch the red control panel to gain lower security access.
Return back downstairs to the statue and cross the room. Press the button to open the door and go downstairs. On the first landing, turn right and go down the stairs here. At the bottom of the stairs, turn left and grab the Flak Shells in the small room. The corridor ahead splits in two directions. Follow either to reach the next door. Inside, you'll see a Skaarj far across the room. Gun him down, then walk over to the computer to get the following message:
"Teleporter target coordinates set for Surface Transporter Pad 13. Sentry personnel already dispatched to location to secure area against resistance. Area cleared for cargo transmission."
Next, turn and press the red control panel to activate the teleporter controls. In the center of the room, a bright light will appear. Walk to either elevator platform, ride down to the ground floor, and step into the light to finish the level.
