A bright red metal gasoline canister covered in rust, still containing some amount of gas. If shot or damaged, gas canisters will explode in a small fireball, which can hurt the player character and other nearby NPCs. Gas canisters are often used in conjunction with traps such as frag mines and gun traps hooked to tripwires.
They can also be connected to environmental hazards such as explosive cars and oil slicks, where one can accidentally set them aflame and trigger fires and/or explosions. If discovered early, they can be gathered without setting off traps or even used to indirectly hurt enemies.
