Gameplay[]

Titan Gas Underground[]

Head to the control room on the left. Hit the switch to open the door. In the large cave area, fly all the way down and head right into a small cave with green beacons. There is a hollow down here, so be careful. Fly around to find a control area with a forklift nearby and some barrels. Blow up the barrels. Inside you'll see a dark staircase. At the bottom is a blue keycard. Use it at the top of the stairs. Inside you'll find an open with red vents. Go through the next vent and up the stairs. You will eventually find a elevator going up. Back outside, go to the right and follow the cave down. When drop down, there's a nearby structure with a gate control. Use it if you want to return, but the hollow is still there. Follow the cave down hill and past a small bridge and eventually you'll come across a structure on the right with an open door. Fly down the elevator shaft and hit the switch. It opens a door behind the window. Go right to get there. Go through a series of caves and you will find a purple switch. An explosion will happen, head there through the door nearby. Keep going through the caves and you will pass a large warning sign. Fly down through the series of caves.

Dead Nightmare[]

Fly past the massive derelict alien ship. There's a nearby lit cave with some equipment. Follow it into the ship. Make you way through the wreckage, past some glowing rods. Eventually you'll see red glowing lasers above, climb up to a vent. On the right is a switch. Proceed forward and you will find a slot for an alien battery. Go out to the purple light trapezoid opening to find a battery. Follow the green light to 5 switches. Go through and you'll find green laser above with a vent similar to what you saw earlier. This leads to another room needing a battery. This area has a Beyonder though. After dropping the battery, again follow the green beam and 5 switches. Head to the hallway with the red and green hexagon, then fly up. Hit the switch and proceed forward. You'll find some stasis chambers. Head all the way forward and you will encounter a new enemy. Press the yellow holographic switch near the window. Head back and down the vertical section and towards the front of the ship. The doors will lower slowly. Keep going forward and turn the vertical shaped switch. This will open 2 hatches with 2 more switches behind you.

Head to the big room with large pillars and purple lasers. Dispose of enemies, hit 6 holographic switches on the pillars and go the center to grab the data. Follow the green lasers. You will eventually find a room with 4 grey pillars in the small rooms. Activate these 4 pillars with batteries. Be careful - each battery insert will spawn a Beyonder, so it must be wisely to bring all 4 batteries to the small rooms first, and then insert them. Quickly follow the blinking green light to the top and use the switch. When the Beyonders are blocked, fly past them. Work your way up the corridors to another data bank. Continue all the way to the front of the ship and and then head down. A Beyonder will appear. Run to the right and hit the switch, then go in quickly. Hit the switch inside, this will put the spaceship into stasis again.

Secrets[]

There are a total of 17 secrets in this mission:

Titan Gas Underground[]
  1. At the end of the initial corridor, to the left side of the catwalk, below the sign "DANGER EXTERIOR AIRLOCK" there's a little alcove with armour and medical sack.
  2. After going outside again, after the elevator, instead of dropping down to the ominous cave, fly up and go inside the upper cave. The secret is the room that's through the airlock. There's a nice slot 7 weapon waiting inside, as well as some creatures.
  3. After hitting the switch that caused a really big explosion and going through the tunnel, the moment there's a holo-sign floating at the exit of the tunnel that says "WARNING: WORKSITE ENDS NO STAFF BEYOND THIS POINT", fly upwards and turn around, hugging the left wall. Besides a glowing crystal there are a slot 9 ammo and armour.
Dead Nightmare[]
  1. When you encounter the very first Beyonder in the ship, jump to a vent where it spawned. Hit the switch at the end of it. Then go back into the hallway. On the opposite side of the big door that's now open you'll find a megasphere.
  2. Requires the trinity key from the secret in Titan Gas Facility, accessed in the indoor area if you backtrack all the way to the beginning after getting the Wing Diver suit in the outdoors. The keyhole for the actual secret is right after the megasphere listed above. Leads to a room with the super secret Beyonder Chibi.
  3. In the big room with the multiple purple switches and the first ancient alien data dump, on one side of the big room is a large crack in the hull of the ship with some ammo on a ledge.
  4. On the way to the final room, you'll pass several yellow shelves. In one of the gaps you can see green light, inside is a magic orb.
