The calculator below (created by Sovq) can be used to calculate effective DPS for any firearm in TLS:DZ. It does not take range or knockback into account, as they don't affect damage and their optimal values are a matter of playing style and personal preference.
Input the weapon data into the "Weapon Stats" block, the results will be displayed in the "Results" block. Since the numbers displayed in-game are rounded, the actual in-game values may differ from what's calculated here.
