In spite of what the game states, animal attacks on your town will typically just lead to the fast death of the animal and some easily situated meat. Do not bother entering into Alarm mode, just select some neighboring villagers and buy them to hunt the animal.

Walls are not required. Just pause the game and hit the'alarm'button as quickly as Raiders appear, to equip your residents and send them to assault proactively.

Raiders will pathfind using bridges you have actually developed, funnelling themselves into chokepoints. Exploit this by organizing watchtowers near the bridge exits.

You will get lots of weapons from eliminating Raiders. Do not bother building late-era spears or swords, you can choose them off dead remains. Bows-- which can be used for hunting-- suffice to be your main 'weapon' being produced.
