Everyone could hear Danh's terrified yelling through the Comms as he whips his weapon out, switch it to full Auto and proceed to mag dump against the tide of spiderbeetles with Automatic MAG fire. Each round ripping, tearing and generally rending good amount of the buggers off, enough for him to finally stand back on his own feet again as he thinned his immediate surroundings.
Then as expected, after several brief, intense seconds of holding the trigger down, his gun started beeping in warning before it begins clicking impotently. The ammo count UI on his HUD showing a red 0/50
And he's still surrounded by a now rather rather miffed Spiderbeetles that's coated in their fellow's gore.
Meanwhile, to those taking closer look and aiming at the giant worm, they'd find it.. actually not as threatening as it first appeared, while it definitely is large and could probably crush you like a bug, it does not have an obvious eyehole. What you thought were it's eyes seems to just be some loose eyestalk from the sludge. It seems to sway a bit, as if confused. Biologists would be able to tell that from the look of those many.. Many teeth, it looks more like that of scavengers, not of predators. Rows of sharp teeth for ripping any big chunks of food apart and the blunter ones deeper inside for crushing it. Those legs does not look like it should physically be able to support it's weight outside of the sludge, so it might only use those to move around in the sludge sea or simply moving food to it's mouth.
You think you've found less of a Giant Death worm and more of a giant living intestine.
