You can kick down any ladders that appear by getting close to them and pressing X/A, depending on your controller. Villagers can still come in through the windows upstairs, but they'll need to use ladders for some of them. You can push the cabinet on the ground floor in front of the window to delay villagers getting in this way. There's a working shotgun hanging on the wall upstairs and some ammo on the bed. Here's some basic tips for surviving in here: From this point on, this is probably your final stronghold, as there's no easy way to leave once you're inside. As you enter, a cinematic will trigger showing Leon locking the door. If all else fails, head to the two-story house next to the tower. Plus, if you find yourself getting overwhelmed, there's nothing stopping you from switching to the other two methods. A quick shot to the head will stun zombies, giving you a chance to sprint by, and dead ends are something to be avoided at all costs. If you go this method, use the whole village to your advantage, luring them around and clearing those ahead of you, while using the map to check routes ahead if you're still unfamiliar. Of course, the downside is that you don't get any rewards off the bodies you kill, including the potential emerald dropped by the man with the chainsaw - and that the game makes you wait longer for the end than if you kill them. Admittedly, it's not easy to avoid taking damage along the way, but it's not easy to do that in regular combat either - and this way you're not burning resources fighting them off. I've tried it, and it's entirely possible to evade the zombie villagers for the whole sequence and never fire a shot. You don't have to kill the villagers, you simply need to survive.
