Military Tunnels

For the Military tunnels you need 1 fuse, 1 green card, 1 blue card ánd 1 red card. And of course you need a radsuit.

Launch Site

To get into the Launch Site, you only need 2 fuses, 1 green card and 1 red card. Together with a radsuit.

  • Puzzle steps
    • Go to the small crude oil barrel building to the side of the dip in launch, inside here you’ll find an on/off-switch. Turn it on. The 2nd on/off-switch can be found just before the sewer part of launch, and can be accessed by going down from this building. This powers the timed switch it can be found by dropping down next to the rocket scaffolding. From there jump over to the timed electricity point. Activate the timer and proceed with the jumping puzzle. On the other end you’ll find a button, give it a press!
    • Now you can head over to the green door, it can be found at the little building next to the three silos. In there you’ll find your first fuse box, put a fuse in it and switch the on/off-switch on that’s next to it.
    • Go through the door nearest to the two blue containers, in that room is the second fuse box with another on/off-switch next to it. This should then unlock the Red Door.
    • There are 4 red doors at the launch site, 2 on each side of the building. When coming from the blue containers’ side you should pick the right door.
    • The way up to launch remains unchanged.
