Vermin Hunter

The vermin are running rampant and the farmers are in need of assistance.
Step into Vermin Hunter and clear out the vermin that are wreaking havoc on the farms. The rats are eating the grain, the rabbits are destroying the vegetable patches and the pigs are eating everything else.

You will earn currency for killing the vermin but be careful, do not kill any of the farmers live stock, because you will loose currency for killing the wrong animals.

Hunt and earn currency.
You will 'later' be able to use this currency to spend on bait to lure the vermin, or better weapons and upgrades to get that kill easier.
So be patient in the beginning, while you hunt with just your air rifle, and make sure you save up as much currency as you can to get those much needed upgrades.
