Utterly Mad

Smasher:
Faced with an overwhelming wave of alien insects, you and your squad back up into the tunnel, whilst firing unfocused at them.

You manage to keep pace enough to stay together, and alive at that.
Soon enough, you've backed up to the intersection again.
A quick glance reveals that the base has gone into lockdown. The entrance is sealed.
"WHY THE HELL IS THE DOOR SHUT?!!!"
The heavy wildly proclaims whilst firing into the approaching wave.

The tunnel leading towards the server storage is still clear.

As an engineer, you figure that you could not just purge the system of the base, but also purge the actual base by venting the toxic gas whilst secured somewhere. That or you could hope that the base is equiped with some armed (and still functional) drones.

You might be able to make a rush to the servers, but that might end up killing someone. Well, except you, being the one to run first.

Lucas:
You leave Wisk to scrounge through his backpack, eventually to withdraw into a garage on the side.
Then it's up the cliffside. The path is rough, even for such a primitive village. It's likely that this path is rarely used.

At the end of the path, lies the rusty prefab house. Looks like it's been roughly put together too, perhaps using poor tools?
Other than the rusty walls, and covered windows, there's a metal door atop a staircase. There's some kind of intercom there.

Oh, and the view of the hidden village is quite nice from here. You note that there are armed hounds patroling about, but there's only maybe 6 of them in total. And there's also a self-propeled AA-gun hidden of to the side, covered by some loose foilage.
The hole in the ceiling of the cavern is big enough to fly in a couple of gunships, one could wager.
If Uniware could find this place, that is.

Strange that you didn't notice before, but there's a smaller lake directly beneath the hole above, with fishing boats in it.

There's also a larger building at the far end of the cavern, on another cliffside(?). It's above the majority of the huts, so it's probably where the village chief is?
