The last weapon from "side weapons" has a very low damage, the single barreled rocket launcher..is this a bug ?? this weapon is the last weapon to be unlocked, it should have much more damage.

Single barreled rocket launcher?

Most under-leveled weapons do inflict more damage than it. Like Rocketful lv60, even have a knockback and has 30 moar avg. damage and heats more for cost of 5 rockets/usage.
