The "KILL AURA" feature, as its name suggests, enables users to automatically kill other players within a certain radius. This is achieved by exploiting Roblox's game mechanics, allowing the user to deal damage to other players without actually having to aim or fire a weapon. The "KILL AURA" feature can be highly disruptive, providing an unfair advantage to users who employ it.

The "HI" feature, on the other hand, seems to be a more ambiguous aspect of the script. Upon further investigation, it appears that "HI" might be related to a form of auto-greeting or chat spam. When activated, the script may automatically send a message, such as "HI," to other players in the game. The purpose of this feature is unclear, but it may be used to annoy or distract other players.

The Roblox Baddies Script GUI Hack is a type of exploit designed for Roblox games. It is a graphical user interface (GUI) script that allows users to access various hacks and cheats, including the notorious "KILL AURA" feature. This script is typically created using Lua, a lightweight programming language used in Roblox.
