Gears are catalog items that usually appear as a tool. They can be worn on the profile of a player's avatar or be allowed in games that have allowed the gear's specific attributes and genre. There are many types of gears, a few examples being swords, lasers, and musical instruments.

Genres of Gear

• Melee Weapon - A close quarter weapon, typically a sword or sharpened edge of some sort, though not always.
• Ranged Weapons - Weapons that work effectively, if not better, on distant targets. Such weapons include guns and lasers.
• Explosive - Items that usually explode, as the names suggest, to clear enemies behind cover, in groups, or for general chaos. Such weapons include bombs and rocket launchers.
• Power Up - Tools that usually enhance the player in some way, such as increasing max health or walkspeed. Some flying gears fall into this category.
• Navigation Enhancers - Tools that help users move around the game. This can be either allowing higher jumps, flying, or by increasing walkspeed for as long as the gear is equipped. 
• Musical Instruments - Any gear that can potentially be used to play music. IE: Guitars, drums, and tubas.
• Social Items - Gears that typically are used for social events. An example is one of the many dancing potions.
• Building Tools - Any gear that can potentially be used to build or modify in-game structures that are not Explosives.
• Personal Transport - Any gears that physically help the ROBLOXian move around the map. A prime example are skateboards.
