Unlike the videos where I use any of the 3 best weapons (Heavy Cannon, Plasma Rifle and Combat Shotgun) wherein I hold back massively by refraining to rely on the crazy broken wombo combo (side shot + spread shot + bounce) in order to show players that Mars Core isn't almost impossible to clear without it, my Chain Gun and Burst Rifle videos feature gameplay wherein I don't hold back at all because both weapons are less powerful at base level and with perks so I try to pick what benefits me the most.
Weapon balance is a joke, hopefully the developers will tweak both Chain Gun and Burst Rifle so they stop being overshadowed by them in terms of damage output and clearing speed.
