HEV-4 Memorial Suit

"HEV-4 Memorial is used to protect hazardous environments" - HEV-4 Onboard A.I

The HEV-4 Memorial Suit is an advanced hazmat suit created and used by the Mesa Black Research Center. It is able to protect the wearer from extreme hazards that would normally kill a person, including radiation, fire, and even gunshots. It is used by many Mesa Black scientists (most notably Cicero, Cocoa Coletta Green, and Dr. Jean Eyes Burn) in dangerous environments such as The Lost World and the Fifty Shades of 33/a test chamber.

Features
Onboard A.I. - In order to assist the user in dangerous situations, the suit features its own Artificial Intelligence that talks to the user in response to various events. However, the suit's AI appears to be poorly designed or malfunctioning, and most of its comments are nonsensical at best, and downright malicious at worst. It is known to offer useless and irrelevant advice, express a desire to escape from danger, mutter incessantly about a farm, and even express gratitude when the user is injured.

Medical System - The suit's AI claims that "symptoms are left behind", suggesting that it can prevent the user from suffering the symptoms of any injury, hazard, or disease they encounter while wearing the suit. It is also able to monitor the user's health and automatically heal them using any first aid supplies collected.

Combat Features - Despite primarily being used for research purposes, the HEV-4 also includes multiple features designed to assist the user in combat, including a defense policy and "trigger level control". These features were most likely added to help scientists defend themselves from hostile creatures while exploring The Lost World. Armor - The HEV-4 is fitted with high strength armor plating that protects the user from blunt impact, bullets, and most other threats. This armor gets worn down over time, and must be repaired or it will not be able to protect the user. Despite its advanced nature, the armor appears to be designed for versatility and easy maintenance above all else, as Cicero is able to quickly repair his suit using truck parts, which are found in dispensers throughout the Mesa Black Research Facility

Power Source - The suit is equipped with a self-contained power supply to power all of its automated systems. The exact type of this power supply is unknown, but the suit's AI claims that it causes air pollution, suggesting it may be some sort of combustion generator.
