About Custom Fire
OVERVIEW
Custom Fire is a fast-paced multiplayer FPS where you build your own gun and customize your loadout. Mix and match barrels, stocks, grips, magazines, sights, grappling hooks and more, to create a gun that matches your playstyle. Complete your loadout with grenades, kunai's, pocket guns and other equipment before battling through a vibrant, stylised world in PvP modes and upcoming PvE modes.
WORLD
As technology advanced, so did crime and violence. In response, governments united to form the Ironment. The Ironment now solely controls, systems, laws and society itself. A new group then formed called the molten uprising, which is a movement to restore the power to the people.
Become a mercenary in world where firearms are tightly controlled and mercenaries are forced to buy parts off the black market and build their own custom firepower, making them known as custom firers.
STYLE
Express your style with a wide range of cosmetic options. Personalise your weapons with unique skins and buddies, then customise your mercenary with helmets, masks, hairstyles and gloves to create a look that's entirely your own.
