don't think i'll be able to but sure!

i go into the snake path room just killing guys with hand gun and then hit the secret door for the count, then back to the corridor for the final door behind which a monster and barrel await,

once dealt with return to now lowered shotty hiding spot, use shotty on other monster, run to corner of snake room to lower elevator, run to elevator and run through the hidden path and then to the exit

my biggest issue so far is getting the aim right when spinning, i keep hitting walls
