Every Pilot needs a backup for those times when their primary weapon runs out of ammo. Although there are only three to choose from, these sidearms have distinct characteristics, giving Pilots ample tactical variety. Unlike the primary weapons, sidearms cannot be fitted with attachments or mods. However, you can complete a number of challenges with each sidearm to earn bonus XP and Burn Cards.
