[8.6]. Mission 6 - Deep Sea: Nullify Threat (2)

Reactivate Teleportals: After the cut-scene, head through the steel door and into the tunnel. Elvis is with you, and he's got his own weapons, so you don't need to babysit him, just try not to shoot him yourself! Once you're through the next door, whip out your IR Scanner. This is key because there are cloaked guards who are invisible otherwise. Enter the next door. You can shoot the red guards if you want, but Elvis is faster and his commentary is pretty funny. Keep going through the giant door up the ramp, then through the next door. Follow the tunnel all the way to the end. Go through that door, and you'll find a tunnel that splits into three paths. The left path has a shield. Head back to the door you came through, and take the right path that leads downwards. Fight your way through the tunnels until you reach an area with a scientist and a guard. Take them both out, and Elvis will trigger the reactivating of the teleportals. He'll run up to the top of the room and up a ramp to finish it. Objective 1 complete!

Disable Cetan Megaweapon: Now, head back to where you found the shield down the left path. Instead of taking the left path again, take the right one. Go through the curving tunnel and the door, and you'll see a teleportal straight ahead – it's that big, moving thing on the wall. Hop in with Elvis. He'll give you the FarSight, so equip that. Your job now is to protect him as you make your way to the megaweapon. Run through the hallway and the next few doors until you reach a round room. Go around the outside of this room and through the door on the other side. Keep going through the next door, and you should see two doors, one in front of you and one to the right. Take the door on the right, and you'll be in the room with the Cetan megaweapon. Elvis will go over and disable it, completing Objective 2.

Secure Control Room: Exit the megaweapon room and take the door to your right. Follow it until you reach another teleportal. Step inside. Now, use your FarSight in front of the door ahead of you to spot and take out the two guards. Go through that door, and Objective 3 is complete.

Escape from Cetan Ship: Approach Dr. Caroll. After the cut-scene, you'll have a strict 60-second timer to get out of the ship. Follow Elvis through the door to your right. Keep following the path until you can turn left. Go through that door, and continue following the path until you see a large blue door on your left. Enter it, go through the next door, and you'll have successfully escaped the Cetan ship, completing your third and final objective in Mission 6.
