Mastaba: "What's going on out there? Unit 3, please respond..."
Marine: "Unit 9 is dead. The hole has resealed, crushing him."
"It must be our target."
I have to go this way, but I don't think the second Marine will fall for the same trick. I'd better just open it up and go finish this in person.
Marine: "It's reopened... I'm taking him out. Fire in the hole!"
Okay, that's not good.
