Assassin

Assassin is a tier 3 copter upgraded from sniper. It has increased bullet size, damage, and speed. Its Damage per Bullet is the highest of all copters in the game; however, a dual gun sniper will deal slightly more damage per shot if both bullets connect on an opponent

Against
Use bullet spammers and get to mid range to attack. Dodging is your top priority if you do not have the speed to close the gap. Ideally, you should chase the Assassin into a wall or corner so you can close the gap as they do not have the damage to fight close range in which case you can start tanking hits to get close.
