Penta-Gun

An upgrade of Tri-gun, which has five guns and also goes well with firing rate, bullet damage, movement speed, you can upgrade to this copter on level 30. It is good for beating heavy copters. It is the preferred build of many top players, including Quantum Cat, and Primus_Invin. Primus_Invin has many world record videos on it, which you can watch on his channel here: https://www.youtube.com/channel/UCpy2Ew5mm3IxIdg1BwduXvA
