Armor effects

Armor effects are a special customizable option in the Armory in Halo: Reach, for Halo: Reach and Halo 4 in The Master Chief Collection, and Halo Infinite. Armor effects are visible in all gametypes, though they are not displayed in cutscenes.

On November 16, 2020, when Season 4: Reclaimer was released in Halo: The Master Chief Collection, it made them available to use on the Elites. In June 23, 2021, with the release of Season 7: Elite, these effects were added into Halo 4 as a new customization option.

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 will play. The effect is seemingly identical to the Grunt Birthday Party skull, which was first seen in Halo 2 without the cheering. The cheering sound effect would come later in Halo 3, Halo: Reach, and all subsequent games.
• Trivia: The clip of sound is a sample from Viva Piñata for Xbox 360.

Living/Death Effects

The following effects are continuously visible as long as the player is alive, with a secondary effect when the player is killed.

Heart Attack

• Effect: Every few seconds, a heart floats out of the player's 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.
• Note: This armor effect has the potential to kill enemies in both firefight and matchmaking according to the Bungie.net heatmaps.

Effect	Unlock (Halo: Reach)	Unlock (Halo: Reach MCC)	Unlock (Halo 4 MCC)
Heart Attack	300,000 cR	Season 1 Tier 65, 1	Season 7 Tier 62, 1

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.

Effect	Unlock (Halo: Reach)	Unlock (Halo: Reach MCC)	Unlock (Halo 4 MCC)

Inclement Weather

• Effect: Electricity and thunderclouds swirl around the player's body. Upon the player's death, a bolt of lightning strikes its body.
• 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."

Effect	Unlock (Halo: Reach)	Unlock (Halo: Reach MCC)	Unlock (Halo 4 MCC)
Inclement Weather	2,000,000 cR	Season 1 Tier 79, 1	Season 7 Tier 43, 1
