The Callipeen is the jack-of-all-trades Jakobs sniper rifle, with a bias towards damage. Low-quality Callipeens will usually have poor rates of fire (less than 1) and will be reloaded as bolt-action.
As quality increases, a Callipeen may either retain a low fire rate and attain increased damage, or attain an increase in fire rate to around 3 and be reloaded as semi-automatic, with a lesser increase in damage. The exclusive pre-order sniper rifle can be a Callipeen.
