Velkon's inventory system is pretty straightforward. You have a loadout, and an inventory.
You can equip a primary, secondary, melee, powerup, and throwable (usually a grenade).
You can also equip cosmetic items like models, hats, body items, mask items, effects, taunts, and more.
You can obtain items through playing the game, trading with other players, or donating at velk.ca/store
(soon I will have a more detailed image)
In the subpages of this wiki you will find info about different weapons, prefixes, talents, uniques, and more.
