Weaker sentry that has lower hp but comes with better aiming that it can hit flying bats very well. The dmg is changed so that it is enough to one-shot bats. Ammo is lower so people can figure out that you have to place it in higher locations so it does not waste ammo shooting zombies. Forget not that the lower hp means zombies can just walk up to it can attack it.
