Fatal Inertia includes random items from weapon pads found during races. These can be used to heighten a racecraft's performance or act as tools to hinder foes. Most weapons can be used as a frontal primary firearm, shot as rear secondary fire, or be used to increase a vessel's speed.
Competitors placed in the last four ranks are likely to obtain stronger weapons, while those in the first four are limited to basic weaponry. Players can discard weapons at any time by pressing the down button.
