If you are having huge problems with finding bandits, go near a town and place down a "Small Shack". They are free to place down like this..
And once they do, you just wait a few seconds and..
Bandits will soon come as they "Discovered" your unconstructed building! Once they arrive, simply lead them to said nearby town..
And reap the rewards.
Be careful to not get too many on you, as If your head/stomach/chest or blood gets too low, you will still die. Although very slowly so.
That, however, concludes our guide for Kenshi as there's little more advice to give other than "Don't forget to save alot" as the game is prone to crashing and other misfortunate events, like you getting a critical hit onto your head and dying almost instantly.
Good luck and have fun!
