You are standing at the hallway where the space suit lockers are at.
2 minutes to impact
As you are dressing quickly in the spacesuits, the movement indicator shows that the invisible creatures are progressing on you.
Hammer is last to start getting in his spacesuit because he had to set up his turret facing out. Unfortunately, it won't see the movement unless something becomes visible. (The turret is set up right at the top of the overhang about where the arrow from "you are here" is pointed.)
You notice the red dot immediately to the west begins moving toward you...right through the wall! Although you don't see anything, it must now be within feet of you.
The dot to the far west is moving down the hall toward you. The two corner dots are moving diagonally
through the walls toward you.
The far eastern dot does not appear to be moving at first. Then you hear a strange buzzing sound (like a mosquito hitting a mosquito attracting light). You look over quickly and see the amorphous outline of a...something...going directly up the far spaceport windows. Some sort of forcefield to protect the windows is wrapping the creature in what appears to be electricity, but does not appear to be slowing it.
However, that gives the creature shape and form for a moment, and Hammer's turret locks on and fires.
It is in that moment that you take a second to reflect on your situation...
1.5 minutes to impact
You have a hostile invisible creature immediately to your west. You are wearing space suits. You have to reach the elevators before impact...
...and Hammer just fired a miniature black hole at a window, on the other side of which is nothing but the void of space and the chance of dangerous decompression...
On the other side of the window, the Pegasus is yawing and tilting, getting bigger and bigger.
But the moment the turret's singularity blast hits the window, all bets are off.
You hear a sound like a concussion grenade and feel something jerking you toward the window. The room is beginning to decompress.
