You follow the sound, which takes you towards the centre of the room and the pile of 8 crates. You're pretty sure this sound comes from there... As you advance towards the pile of crates, you notice some sort of machine in one of the alcoves. It is running, but also riddled with holes, similar to what those strange creatures did to your escape pods. There are a few sparks here and there indicating the machine is damaged...
Then one of those creatures exits one of the holes. Spotting you, it tries to make a beeline for you, but the machines makes a strange whirling noise and sparks a lot at that point. The creature stops and seems to be screaming in pain for a few moment before exploding in a gory fashion. Then the machine short-circuits and shuts down, and the lights in the hangar goes off, plunging you in total darkness, aside from the bit of light near the opened doors at the entrance.
And the scratching continues, somewhere inside those crates, near you, in the dark... Hope you have some sort of lighting source...
