I use my first action to move into a farther room If I can, and second action to shoot one of them from the cover of the door gap.
[Roll HP, semi-auto; 02 out of a natural 40 (That's two hits, I suppose, So I'm rolling two damages) -> Dam 1 = 6+2; Dam 2 = 4+2]
If I cant, I shoot from the door of the room I am and try to close the door and lock it after that, If not, I would just walk backwards, my back agains the wall, trying to cover with any furniture, if there's anything suitable.
You take cover at the door to angevins room and even as the figure tries to dodge your shots, you place your 2 hits well.
They have a defence of 5 (1 armour + 4 TB), so the man takes 3+1=4 damage and is lightly wounded.
