The angler is a tier one tank, upgraded from the Basic Tank. The angler tank features two barrels, spread around 45 degrees from each other. The barrels' bullets do more damage than a twin, but are more spread out, making it harder to focus both barrels on one enemy.
The Angler has a better dps, to compensate for its spread. On focus fire, it is worse than a twin or a machine gun, but is a lot greater for farming. It is suggested not to attack other tier one enemies, other than the flank guard. Stay near the pentagon nest, as farming is much easier.
