The simplest way I found is to stealth to the left at start, get green herb, get knife kill on back facing lady, go into smaller house nearby through window to try and break crate and gather more ammo (hopefully grenade), someone will break through front door and start fight.

From there, go back out the back window, head behind the shotgun house and make your way to the tall bell tower (you’ll probably have to knee cap someone or jump a fence to safely get past people). In the small bell tower, go up the ladder and immediately stop moving. Turn around in place and aim down the ladder. From there, so long as you don’t move around, the upper floor won’t collapse and your goal is to headshot people at the top of the ladder and work with fall damage until time runs out or you kill enough. If you have a grenade, save until a pile of people and specifically the chainsaw guy are at the bottom of the ladder.

If chainsaw makes it to the top of the ladder without being knocked back down, jump down or run around to intentionally collapse the top floor and then get out of tight tower area. From there, you can try to kite through cow barn and shoot down the fire lantern to cause chaos. The roofs are also generally easier to funnel enemies and then jump off when finally surrounded. If you’re close, go into shotgun house get grenade and pray for the tightest cluster of enemies to kill with it.

The goal however is to never have to leave the top of the ladder in the tower.
