Somewhere in the late 2020s or something. I don't know.

You're you or whatever, just- someone that works here in the Black Mesa Research Facility. You're getting pretty damn close to the surface now, however one more airstrike might just cause everything to collapse on you... You find a lift, and take it.

As you reach upwards and onto the next floor, and step out the lift, you hear footsteps. Immediately growing wary, you take cover behind a crate quick, and peek from the side of it, trying to figure out whoever it was that was walking...or what it was...

However, you see an H.E.C.U Marine looking around paranoid, wielding an M16A4 ACOG. He has a white camo uniform, black fingerless gloves, an M40 gasmask with green visor eyes, green camo helmet, a black P.C.V (Powered Combat Vest), black boots, and an IFAK Pack strapped to his belt. He then conveniently, shines a flashlight onto your hiding spot, and sees you.

"HEY!" He shouts out, the tension prominent in his voice. "COME OUT FROM HIDING, WITH YOUR HANDS UP!" He orders with his M16A4 ACOG aimed straight at your position. What do you do?
