How do you beat the last guy?

I am getting pissed now.

Over 800 bullets, 24 sniper bullets and 5 mines and he isn't dead.

I just started this game yesterday and might be doing something wrong.

key= stay in the light, and lure him to the door when u come out of, then book it for the turret on the back of the train platform, and rape him

stay in the light tho

thats the easiest way

that work but if ur on casual u can actually book it right away
if on hardcore its a bit harder also grenades work in moving bats away which shield him.
maybe u didnt know this but that bats shield him so u have to scader the bats some how and the shot him. grenades work when bats are arround him or wait till bats attack u and shot them and theyll scader for a few secs

use a sniper and just wait for him to shoot the bats at you or w/e then shoot him in the face

Just wait till the Krill get away from him and Headshot him (while the krill are away)
Should go down pretty quick pending on difficulty

get the krill off him with a torqe bow or frags then headshot him as many times you can before the krill jump back on him. stay outa the dark but keep distance

Well, I like grabbing a Torque Bow in the earlier stages and save it for him, then throw a grenade at him, or something to get the Krill away from him, then Torque him right in the face

Or any weapon will kill him, it is just the better the weapon the faster he dies

And remember to watch out for those reavers on the sides of the train
