The weapons range from a pistol to a cannon that shoots a bolas weighted by grenades. The player can aim down the weapon's iron sights or optical sights for increased accuracy. Each weapon has an "alternate fire" mode which uses charges; for example, the assault rifle's alternate fire is a single blast of bullets that destroy almost everything in its path. Much of the story and gameplay revolves around the "energy leash", a rope of energy projected from a device on Grayson's left hand. The leash allows him to pull enemies towards him, activate certain devices and traps, and slam down a ball of energy that launches all nearby enemies into the air. The player can also kick enemies and run and slide into them. If an enemy is launched into the air from the whip or by being kicked, the enemy goes into slow motion to allow the player more opportunity to perform skillshots.
One of the game's unique features is the "skillshot" gameplay system, which rewards the player for killing opponents in the most creative and destructive ways possible, from killing an enemy in midair to pushing an enemy into a carnivorous plant to executing an enemy after shooting him in the testicles. The more complicated or unusual the skillshot, the more points players acquire. The points are used to purchase weapons and upgrades. The weapons are unlocked at set points throughout the game, and after a weapon has been "re-armed" by purchasing it, a "charge shot" for the gun is unlocked at another set point.
Points are used as currency at "dropkits" scattered across the planet, which the player can use to replenish munitions. The dropkits include a gun shop, a skillshot checklist, and gameplay statistics. The player cannot upgrade their weapons, but can equip different guns, purchase ammunition, upgrade the amount of ammunition they can carry, and even purchase special-ammunition "charges". The player can equip up to three weapons, the assault rifle being the default weapon; it is always equipped, and is considered the main prop weapon in cutscenes.
Bulletstorm uses a recharging health system, in which damage to the player is reflected by the screen turning red, and the player quickly returns to full health when not taking damage.
