Unit 7 - Level 6 - Outlands

Objective: Retrieve the airstrike marker, then place it in the receptacle beside the fuel pod.

U7L6W1 (strategy)

Turn the corner slowly to go outside and notice many soldiers and an Enforcer sitting behind a huge canon that swivels around. Use the cave wall as cover, choose something mighty, and start plucking away the guards. If you use the crosshairs on the screen you can aim just over or under the cannon to kill the Enforcer. Watch out for the swarm of Flyers once you kill this dude.

U7L6W2

You can now either cross the bridge towards the cave doorway or hop in the water and battle Barracuda sharks all the way around to dry land on the other side of this mountain. First pick up any health, ammo, and armor and then dive in the water if you want to battle the Barracudas. 

U7L6W3

Walk up onto dry land and finish off the guards. Pick up the health, ammo, and more importantly - the airstrike marker. Walk up to look for more Strogg to blow to smithereens while you look for a receptacle to place this marker beside.

U7L6W4

If you jumped in the water, and you didn’t take the cave entrance on the other side of the bridge near the cannon, then go there now and kill the guards and Enforcers if you’re still in the mood to kill Strogg. They way you get there is as follows: when you came up out of the water to snag the airstrike marker, head left over the ledge to the other side.
When you’re done (you see the canon again), return back to where you picked up the airstrike marker and then head deeper into the cave towards the fuel pod.

U7L6W5

Battle the Flyers, black guards, and Gunners and look for the fuel pod along the red pipes. Once you put in the marker, you have 10 seconds to get inside on the far door to avoid the Terran airstrike. This shouldn’t be a problem for you since the guards are running out! Grab the bandoleer and silencer or any other items you can use when you’re in on the inside. After the strike has been completed, you must now proceed to the exit, which can be located at the far door outside near the fuel pod. Good job! And off to Unit 8…
