How do I beat this level? I kill everyone in the Church, but then out of nowhere those guys open the doors and come in huge numbers. Any tips or suggestions?

I forget where but there is some health in the church, try killing all the guys first and before you go up to that door where they bust in get the health. I think i remember them having shotguns, the best thing to do is to take cover and when they are reloading start fireing at them.

the only thing u need to is run up and they will com upstairs one by one then shoot them there and when u think u got all of them go down and go into that door

Hey If You Got Low Health Then When You Go Down The Stairs Get The Health Pack Then Go Into The Room Shoot Everyone Up When The Guys Start Coming Crouch Down Behind The Chairs Shoot Trough The Chairs Or Take Out The Colt And Shoot Like Hell There Thats Pretty Easy To Me
