The Twin Flank is a Tier 3 Tank which upgrades from the Flank Guard and the Twin. It has four barrels on the tank -- two on each side.
The Twin Flank features a circular base with two barrels on the front and back.
One gun from each pair fires then the others do. Selected first guns are random with every shot. A cycle with this tank consists of four bullets. This class gets a base stat debuff to Bullet Damage and a base stat buff to Movement Speed and Reload.
Strong against: Spread fire type tanks, tanks with average to low Penetration, rammers (if using a bullet build), low level tanks
Weak against: Focused fire type tanks, tanks with good Penetration
As the Twin Flank
Your bullet spamming should be able to ward off any tank that you cannot kill for the time it takes to retreat. The Twin's good Bullet Speed gives it surprisingly good Penetration for a tank with a debuff to that. Keep that in mind when attacking. Also, don't hesitate to use AutoSpin. Don't get scared of being flanked.
Against the Twin Flank
Avoid its bullets as they penetrate more than most players think. Don't approach it from the front or back. Be careful if the enemy Twin Flank activates AutoSpin.
- Use a Focused tank like the Triplet, AutoGunner or even a Twin.
- Max out your Bullet Penetration with something like a Destroyer or Penta Shot.
