Health pack
From Halopedia, the Halo wiki
The UNSC uses the Health Pack as the standard combat wound treatment, which is used by all combat personnel, ranging from Marines to even Spartans. Each Health Pack contains an amount of biofoam, a stitch kit, polypseudomorphine, self-adhering antiseptic battle dressings, and other useful field dressing components.
Health Packs are standard requirements aboard many UNSC ships for medical events. Health packs are often seen on corridor walls at regular intervals. There are also two health packs located in a Pelican. Both of them are on each side of the door to the cockpit. They seem to be more rectangular in shape and are inaccessible to the player.
The Health Packs are present in Halo: Combat Evolved and Halo 3: ODST only. In Halo: Combat Evolved, the Health Pack would fill the player's health, but would have no effect on their shields. In Halo 2 and Halo 3, health regenerates with an integrated biofoam dispenser within the new MJOLNIR Mk VI. In Halo 3: ODST, the health packs are dispensed from Medical Kiosks and they use a healing agent known as MediGel.
Trivia
- There is an unexplainable glitch in Halo CE. If a player is standing on a health pack, and hit by a tank shell, they will survive. A tank shell has enough power to kill a fully shielded player two times over, so the numbers don't add up.
- When you pick up a Health Pack, you will become momentarily blinded by a white flash. However, this goes away instantly if you go through a teleporter.
