Tunnels 15 :
run to the top left, to the leftmost corner next to the building, end turn without shooting/killing the weak zombies
the boss should be within your range, shoot him, the weaker zombies should now surround you, and prevent the boss from reaching you
now just tank the weaker zombies surrounding you while you kill the boss
To Devs: Strength 15 (including items), specifications on character screen show that I have movement range of 5, but no matter what I try I cant move 5 tiles in combat.
Straight, diagonal, around objects, always caps at 4.
With viewing range of 5, moving 4 tiles diagonally ends in going out of vision range, so vision shouldnt be an issue.
