*Plays the Valve theme song as wears the suit*

HEV, an abbreviation from "Hazardous EnVironmental suit". It has a built-in flashlight, oxygen supply, Geiger counter, morphine administrator (which allows the user to function normally even after serious injury), anti-toxin delivery system, an optional long-jumping module which allows jumps over large distances, a radio, many tracking devices, and a heads-up display (HUD) which tracks health status and weapon ammunition usage, as well as including a weapons management system. The suit contains an on-board computer system that constantly monitors the user's health and vital signs, and reacts to any changes in the user's condition. Additionally, the suit features "high impact reactive armor", an electrically powered armor system that can be charged by power modules throughout Black Mesa. While charged, the suit provides greater protection from injury as the charge absorbs more than two-thirds of any damage or trauma experienced by the wearer. With a fully charged suit, the wearer can survive several dozen bullets of small arms fire or even a direct hit from a rocket propelled grenade.

...and even Wikipedia knows that this suit is a must! F*ck Master Chief's stuff, I want THIS! His suit ain't tellin' how healthy you are, or give you antidote for poisons.

Coloured version coming later!
...And yes, I am STILL alive!
