Override Reactor

The Override Booster is an item in Hazard ReBurst that supercharges one's avatar to allow them to compete with dangerously powerful enemies. Given that it enhances a player to high levels in order to put them on par with dangerous enemies, the Override Booster is an item so rare that no player has even heard of it; even some of the beta testers are unaware of its existence.

Design
The Override Booster is a small handgun-like item, with a short barrel and a hexagonal length of a durable, transparent substance in the hand grips. The body of the gun is dark silver with a hexagonal overlay and black hand grips. The transparent window in the handgrips serves to indicate the amount of energy left is left in the Booster, as its energy source comes in the form of a detachable battery in the shape of a firearm magazine. Once the battery is loaded, the window on the Override Booster's grips will light up depending on how much charge the battery contains; the battery, when fully charged, contains enough energy for 5 shots.

To use the Override Booster, simply insert the battery into the gun, then pull the slide back to transfer energy from the battery to the "chamber" of the gun; the slide will automatically spring forward, just like racking a handgun. From there, the user aims the barrel of the gun to any part of their body, usually one's head or arm, and pulls the trigger. The energy stored in the "chamber" of the Booster will immediately inject itself into the user and override their avatar's limits and significantly boosts combat performance; hence the name "Override Booster." Of course, the user can fire off all the energy in the battery, but doing so is dangerous and may cause an overload that results in death rather than boosting the user more. Using the Override Booster just once is already dangerous enough as is, since the enhancements cause an intense strain on the user.

Given the nature of the Override Booster, its augmentations are temporary, with the time limit depending on the user's stamina and resistance to the strain. When the user first uses the item, the effects may last anywhere from 1 second to 1 hour depending on the given circumstances; on average, the first use of the Override Booster results in a five to ten minute boost, though the time does vary. After this first use, the user will collapse from exhaustion and they may end up unconscious for a day or two depending on the effort exerted during the first use. Once recovered, players are advised to wait at least a month before beginning training to successfully use the Override Booster for extended periods of time.

Trivia

 * The Override Booster is based off the Ruger Mark IV 22/45 Lite pistol and the Evoker from Persona 3 in terms of appearance, and the Hazard Trigger from Kamen Rider Build in its functionality.
