The Teaser is a weapon that is only featured in Grand Theft Auto: Chinatown Wars. The weapon is considered as a melee weapon, so the weapon occupies this weapon slot. The weapon was set to feature in Grand Theft Auto: Vice City as a primary weapon for the Patrol Invest Group, but was removed.
The weapon launches a small wire, which then attaches to a target and stuns them. It has a power meter, which starts at 100, then is depleted with use, then slowly recharges overtime. If a victim is shocked by a Teaser for a long amount of time, the victim will then catch on fire, and the player will immediately gain a one-star wanted level. The Teaser can't be found on the street, but can be purchased from an Ammu-Nation for $300.
