Feeling the immediate tensions, everyone immediately jumps to cover and prepares to shoot each other (+5 Prone Ttney ++5 attack, +10 Fniff for corpse concealment, +15 for thick steel door. Numbers all sound fair to everyone?). Everyone fires their prepared guns, right after jumping to cover without taking time to properly aim (-15. Can't hit nothin like that without luck or skill!). (I rolled a dice three times to check order in the order you posted. Tntey first, Prophet last, Fniff second). Tytey begins wildly shooting off his prepared shotgun, causing the other two to retreat further behind the cover they took (+5-15 Roll 21=31, a pass. No specific target, so I treated it like suppressing fire. I decided to roll 1d5 shock without a multiplier, rolling once for each of you and getting two 3s meaning you are rather effected. Both of you receive an additional -5 penalty) Meanwhile, Fniff sees Tntey closest to the ice cream, and proceeds to blast away from the hip. (-15-5+1. Yep, you should probably get critical effect of some kind, from rolling a 1.=19) The blast removes Tytney's head, the sound of the gunshot echoing with the sound of cracking flesh. Lucky everyone has earplugs, or you would all have gone def or mad. (1d10=6 lethal, 1d5=5 shock. 5*6=30 lethal he is dead). Profit finally acts, peeking the shotgun around the door to blast Fniff. (32-15-5=52, a near miss), it sprays blood as the corpse hood swings back and forth, but it doesn't pearce to Fniff.

What do you guys think so far? I don't really like the 50/50 nature of it, if I added better/more/bigger modifiers than I did now it would probably work out better.
