in celebration in the creation of this category, i decided to try and find a route for brest
video link
i can already see possible improvements though, like maybe going in reverse (maybe fight less dudes?) or getting a guy with better healing (less first aid uses: this is a sabre squadron mission, no instant healing, so less health per heal is a time loss)
tl; dr for the video though
walk up to the big gate
crouch clip through it
crouch clip through a smaller gate towards the fuel tanks
bomb fuel tanks
gun it towards the beacon (metaphorically and literally)
get stuck looking for possible crouch clips out (so i dont have to lockpick)
give up and lockpick the gate to the beacon "room"
run towards the docks, fight + bomb boats
waste time healing
crouch clip out
grenade the last few soldiers along the way
exit and victory
