In addition to his fists, Jimmy can use various weapons against his opponents. All items are non-lethal, and do varying degrees of damage to other students.
To select a weapon from your inventory, use or to scroll through the available items. To fire or throw the weapon, press - locking on with is optional.
For thrown items and the slingshot, holding will increase the power of the shot.
Slingshot
The slingshot is Jimmy's basic ranged weapon, which fires small pellets. You've got infinite ammo with this weapon, so it's a good one to fall back on. Jimmy gets the slingshot by beating Davis in The Setup, and an upgraded version with a scope is unlockable by successfully defending Earnest in The Candidate.
Firecrackers
Firecrackers are one of the most powerful weapons Jimmy can use, but you're limited to only five in your inventory. A well-placed firecracker can take out an enemy in one hit, but if Jimmy's too close he'll take damage as well.

Stink bombs
Stink bombs don't actually damage the person they hit, just annoy them. They'll be preoccupied enough to allow Jimmy to make a quick getaway if you need to. Jimmy can't attack if he's too close to a stink bomb explosion, as he's too busy holding his nose. Jimmy's inventory can hold five stinkbombs.

Itching powder
Like stink bombs, itching powder doesn't hurt your enemy, but it will distract them. This item is very useful against stronger enemies, since you can use it to distract them briefly and land a few quick blows while they're out of commission. Jimmy's inventory can hold five packets of itching powder.

Eggs
Eggs can be bought at any convenience store, or found in Jimmy's room after The Eggs. They deal no damage, but if you hit an enemy in the face they'll be temporarily blinded. Each carton you find holds 12 eggs.
Marbles
The only remotely defensive item, marbles can be dropped behind Jimmy to trip up any pursuers as well as thrown at a target from a distance. Jimmy can hold up to five bags of marbles in his inventory.
Bottle rockets
After the Nerds Challenge mission, Jimmy will be able to use the bottle rocket launcher. The rockets are about as powerful as firecrackers, but the gun isn't very accurate at long range and the fire rate is quite slow. The explosion can hurt Jimmy if he's too close when the rocket hits. Your inventory can hold 12 rockets.
Spud gun
Unlocked after the Stronghold Assault mission, the spud gun fires whole potatoes at a target, dealing a large amount of damage. The gun can also knock out most targets in one hit, but can be innacurate from a distance.
Other items
In addition to outright weapons, the following items are available and used in much the same way.
Skateboard
The skateboard can be selected and put away like any other weapon, or using the + shortcut. Tap or hold to speed up, and ollie with . The skateboard can go down stairs, but Jimmy will trip if you try to go up.
Camera
