Been thinking about this for a while. got easier after this update with handling the shamblers, but the zappers became menaces! especially the one at 28:08 ! The nock is the best for this by the way. The penetration is simply necessary... Something else I noticed was the Rifle is pretty solid for this. (although slower) Blunderbuss can work. This route can be used by any class, it is very consistent. Might attempt w200 later.
although depending on class you'll set off bombs differently. If you're using the musket or a gun with less penetration, stand on the stairs in the Big Red House and shoot bombs as they come in. As medic and priest, just loop and set off bombs through the walls. Sapper I don't really know about, and there is probably a better route for.
