Pioneer One

Pioneer One
A large military mining station on the surface, with lots of items and materials. This building is where you will find the level 0 keycard.

Map
Shortly past the entry door to Pioneer One there is a map showing the layout of the facility.

This map doesn't show some rooms(e.g. teleporter room, Dr. Hahn's room).



Trivia
On June 10, 2013 a prototype area of Pioneer one was shown in this blog post, including a map that was extremely different from the current version.

Unfortunately, this map never made it into the game and Pioneer One has stayed the way it is shown in the heading above.

Getting Inside
Shortly after reaching Pioneer One, you get the urge to get inside it. The door is locked, there's no open spaces and you are getting more unpatient within seconds. But luckily there is a way inside.

Pioneer One is situated right beside the Mining Operations Base. That is, you will have to walk in the direction to which the door of Pioneer One for about five minutes. Eventually you will reach the Mining Operations Base. The door is locked too, but luckily the window is destroyed, and that is your way in. Search around, and you will find some barrel explosives. You then bring this back to Pioneer One and place it close to the window. You will now need a Firestarter tool to light it (I assume you have one of these by now). I advise you use only one barrel explosive and save the second one. Make sure you stay well away from the explosion, it's probably bigger than you expected.
