Activate your Searchlight and follow the corridor around to the right. Kill the Pupae that attack you from the dark passage. Ahead you’ll see all those items that were behind a force field are now easy to get. Grab the Eightballs, Flak Shells, Med-Kits, Tarydium Sludge and Flares then drop down the shaft behind them.
Below you’ll find more goodies, including some Rifle Rounds, A Shield Belt, ASMD Core and Bullets. Stock up and take on the Skaarj ahead. You are in the Mothership Lab, near the original starting point. To reach the Core, follow the passage on your right. Keep following it through the doors ahead, and you will
eventually reach the central lift that links the Lab to the Core. Enter the Core and kill the Mercenary on the lift.
Upstairs, turn right the left and go down the short stairs. On your left is another area that was previously protected by a force field. Kill the Skaarj inside and get the Super Health Pack and ammo inside. Follow the corridor and make your way back to a small chamber. Get the items inside and make your way down stairs past the steep ramp. There’s a Skaarj Gunner lurking ahead, let him have it and ride the lift upstairs.
Turn left and take on the Ice Skaarj to get the doors to open. Inside follow the passage on your right and approach the holographic console to gain authorisation to turn on emergency power. Return to the other room.. Walk down the raised trench to start the secondary source, then step through the doors.
