How about the opposite direction of the angry Genestealer noises that are slowly getting louder for a start?

Whelp, time to see if your body has kept up with its cardio. You decide that going away from the spund sof encraoching **** is better tham being here and bolt in the opposite direction of where you percieve them to be xoming from. This proves to be a wise choice as a fucking Genestealer enter into the small pool of light you were just standing in and...HOLY SHIT her tits are HUGE!

OH YEAH FOR YOU SHE HAS A PAIR OF FUCKING FRIENDS!! TIME TO GO FASTERRRR OH SHIT! THAT solid metal wall got cut like nothing and that was almost your face. You know it may not do much,but it'll hopefully slow them down enough for you to get through a damn door and lock it behind you. Taking one of the grenades feon your belt, you pull the pin and count to four before tossing it in the face of the closest xenos and glance back to see it has the desired effect of giving about two seconds of extra breathing room Juuuust enouhh time to go thepigh the neareat door, close it, engage the lock aaaand gaunts.

Three of them...and you locked the fucking door. This universee is officially trying ita damn3daest to kill you. You shouldn't be surprised, its considered by many to be the embodiment of the term "PC meat grinder" for a reason. You continuento stare at the three human sized tyranids and wonder if you should shoot yourself in the head qith your lasgun, it'd be quicker and far less painful.
