I hadn't given too much thought to it at the time of posting (it was late) but it would be something like this:
Traps
There would be several types of traps that you could build. Some would be associated with walls some free-standing
1 - Wooden spikes. These would be similar to a fence in cost, but wouldn't need to be cleared up when destroyed. Chance to impale creature for extra food. Would have to be built infront of wooden or stone wall. Would have only one use/hp. (all amounts possible to change)
2 - Earthen pit. More effective in front of wall. Would trap smaller creatures and tire out larger creatures for less damage when they hit (and for stone walls, likely no damage. Eg: bear and boar would now do none, monster would now do 1). Could be used several times, although might need to be re-covered (disguised) again. Maybe a chance for food? Would take several villagers but no resources.
Other types of traps still to be considered.
Weapons
A person would have a chance to find iron in the deep forest. With this iron they could then craft an anvil, and then a weapon (pike/spear or sword). Possible other items also. This would then either give them a chance to defend their house should it be attacked and there be an attempt to take a family member, or an option to station themselves at a wall to decrease damage to it (but it would use up their action for the day).
It's not much, but a work-in-progress.
