Chemrail

The Chemrail is the 22nd gun available, is unlocked at level 32 and has an 80 round clip. It boasts very high damage and accuracy and high range, as well as moderate agility.

Strategy
The range of this weapon is very long for an automatic weapon, and the combination of the high damage and large clip size of 80 bullets make for easy kills. The Chemrail has one of the highest DPS (damage per second) of any assault rifle or machine gun, second only to Siege Cannon. Because of this, players can last longer in fights. This is an all-around, reliable weapon for any fight: large clip, fast fire rate, high damage, and long range. This makes this weapon very versatile, and players can adapt to most enemies in battle using this weapon.

Counter
The Chemrail does have one weakness: burst damage. Revolver, blunderbuss, shotguns, and howitzer are all good counters to this weapon. Chemrail is best at mid range. At long-range, the Howitzer Gun can easily defeat this weapon. At short range, Blunderbuss and the Shotgun can put out high damage in a short amount of time. Revolver; however, is the only weapon that will counter Chemrail from any range.
