When you play as a marine, I suggest that you get immersed into the world and character. If you are in pain, roleplay it out, either groaning, complaining, limping, etc. Emoting changing out dirty bandages or covering wounds with an ice pack. Remember that normal combat with other human beings is a thing that causes a great many people to have PTSD, leading to substance abuse and other not good things, and that’s against humans, you are fighting the perfect organism: the definition of murder given chitinous flesh. You should expect to panic, to flip out, lose your shit, misfire your gun at the smallest noise, and hallucinate seeing gigerian figures in the darkness.
My last point is: if you get captured, panic, panic panic panic. Ellen Ripley (and to a lesser extent Cpl. Hicks, newt, and Amanda Ripley) are veteran bug killers/survivors, and they panic at the sight or suggestion of xenomorphs, they see them in constant nightmares to the point they cannot function. Your marine, who in all likelyhood has only ever seen a bug in some kind of briefing document, should be having the worst day of his life even if he survives. If your marine gets captured, this should be your shining moment to show just how fucked your marine’s brain is.
Pray for death, call for god, buddha, or your mommy, scream and shriek and try to kick the xenomorph futiley in the face. You are a redshirt, even as a specialist, or tank driver, or Commanding Officer. The most badass bug killers in the galaxy cannot keep their shit together just seeing bugs in their nightmares, you will not do any better than them, do not calmly call out you’ve been captured and give your location, scream your location out on general comms and cry for anyone to save you, or go completely catatonic and non responsive but using emotes. If you see a fellow marine getting captured or torn to shreds, panic like an Xcom character and fire wildly in their direction, or run with all of your life away to the safety of the fob, even against command’s orders.
Yes, I’m saying fear RP more, bite me, it’s great for immersion and I like to do it, nobody will remember who won LV round 5k.55.
