Ok, just need some clarification:
Niil checked a sigh of relief; at least the lift didn't have a surprise inside. "All right, at least we can use the lift for some cover if the drek hits the fan. Mariah, try to pop that exit door open just above us. Everyone else, get ready for covering fire.
So, you guys are standing on top of the lift at the bottom of the shaft. Going into the lift and through it's door would put you on the lowest level of the facility, where the power core will be. But you want to, from the top of the lift, go through the second floor access door?
It's fine, just want to make sure I understand.
Going through the lift puts you on the 1st floor. Going through the access door above the lift puts you on the 2nd floor.
