Jex, Mariah and Collan drop down to the next blast door, and Mariah gets to work. She finds the actuator panel easy enough, but this time there is no handy power feed to drive them. Feeling the pressure, she pulls four spare power packs from her armour belt and begins to wire them together. It takes about thirty seconds, and there is a fair bit of cursing from her as she gets a little singed. But you are rewarded with an audible click when the interlocks disengage, and the door slides open slightly. Mariah yells "Down!" a moment before her rigged power supply detonates, scattering (mostly) harmless shrapnel around the area. Aside from some singed fingers on Mariah an minor cuts and burns on Jex and Collan, everyone is fine. It takes Jex a little effort to force the doors open, but with feet and hands me manages to force the doors far enough apart to fit through. Still no sign of hostiles.
Below you, you see one more exit door in the side of the shaft, and below that the lift. It looks like there is an unexpected lower level to the facility. Not a total surprise, given that there was apparently an Intel base here, and it changes the plan little. The reactor will be in the bottom of the facility, and that's your goal.
[Actions?]
The lift is blocking access to the bottom level, but it should be fairly easy to blast through.
