Armor effects
From Halopedia, the Halo wiki
Armor effects are a special customizable option in the Armory in Halo: Reach. Armor effects are visible in all gametypes, though they are not displayed in cutscenes.
On January 2020, when Season 4: Reclaimer was released in Halo: The Master Chief Collection, it made them available to use on the Elites. In 2021, it was revealed Season 7: Elite will make Halo: Reach's Armor effects available to use in Halo 4.
Death Effects
The following effect occurs when the player is killed.
Birthday Party
- Effect: When a player dies, confetti explodes out from their body and a clip of children cheering ("Yay!") will play. This effect is extremely similar to the Grunt Birthday Party skull from Halo 2, Halo 3 and Halo: Reach.
- Trivia: The clip of sound is a sample from Viva Pinata for Xbox 360.

Heart Attack
- Effect: Every few seconds, a heart floats out of the players body and disappears. When a player dies, several flying hearts will appear around the body of the player.
- Trivia: The hearts are actually based on a temporary effect used by Bungie effects artist Steve Scott for debugging. The effect is also seen in the "Dancing Marty" easter egg in Halo 3: ODST.[1]
- Note: This armor effect has the potential to kill enemies in both firefight and matchmaking according to the Bungie.net heatmaps.[2]

Pestilence
- Effect: Bugs and a cloud of green flows around the player. When hit, instead of blood, the player bleeds a green liquid similar to the pus-like fluid which is seen when shooting Flood forms. Upon the player's death, he/she explodes in a manner similar to a Flood carrier form. Occasionally the cloud will be red instead of green.

Inclement Weather
- Effect: Electricity and thunder clouds swirl around the player's body. Upon the player's death, a bolt of lightning strikes its body.[3]
- Trivia: This Armor effect's name is possibly a reference to Cortana's comment on Halo's climate as heard on Halo: Combat Evolved campaign level Assault on the Control Room; "Interesting... the weather patterns here seem natural, not artificial. I wonder if the ring's environment systems are malfunctioning... or if the designers wanted the installation to have inclement weather."
