Hero Units

**Hero Units** are special units that appear in *SPV3*. They consist of characters from the main narrative who will help players in both Campaign and Firefight.

## Overview

In *SPV3*, Hero Units are essentially the in-game representation of characters from the story. Like Marines, ODST's and even Sentinels and Enforcers in certain missions, they are allied with the player and will help fight against enemy factions.

Unlike typical reinforcements, Hero Units are invincible. They will never die regardless of how much damage they endure on the battlefield, as their plot armour will not allow them to be killed. However, they can sustain enough damage that they will be injured and knocked down, and thus, leaving them unable to provide aid to the player. To counter this, players can approach them and press the action button to revive them, the idea taken from the squad mechanic in *Halo 5: Guardians*. Unlike *Halo 5* though, there is no real-time animation for the resurrection, Hero Units in *SPV3* will be revived instantly.

A Hero Unit is the reward for completing a round in Firefight. By surviving wave 10, a Hero Unit will spawn and fight alongside the player until the game is either won or quit.

## Trivia

* In *Halo: Combat Evolved*, Sgt Johnson and Captain Keyes were the only story characters who appeared in-game. However, Johnson was not an official character at that point, his model being used for several allied NPC's. Keyes, on the other hand, was unique, appearing in *Truth and Reconciliation*, but he could be killed. Players would be reverted to the last checkpoint if he died, and he must be protected all the way to the end of the level to proceed with the story.
	+ Captain Keyes was also killable in the *Pillar Of Autumn* in *Halo CE*. This could only be done by the player, however, and if done, Invincible Marines would spawn and attack the player until the player was killed. This was done to punish players who betrayed allies. Cortana even had a line of dialogue should players choose to trigger this event. Since Keyes is invincible in *SPV3*, the Invincible Marines have been removed from the game altogether.
* If a Hero Unit is knocked off or falls off a cliff, they will be respawned back to the players location, similar to how players would respawn in co-op playthroughs of *Halo CE*. The only exception to this, oddly, is Johnson in Halo. If he is knocked off the cliff at the start of the mission, it counts a a game over and reverts the player to the last checkpoint.
* Keyes and Johnson are the only Hero Units who use different weapons depending on their appearance.
* *SPV3* Firefight marks the only appearance of Foehammer as an interactive character. She is unseen in campaign or any of the official *Halo* games. The voice clips of the female Marines in *Halo 2* were used for her field dialogue.
* ONI Agent Joness, Rtas 'Vadumee and Usze 'Tahamee are the only Hero Units absent from Firefight.
* Usze 'Tahamee shares the in-game model of the regular Spec-Ops Elites, except is armour is red instead of black, to match his appearance in *Halo 3*.
* Brandon is the only Hero Unit who doesn't have a unique character model.
* In *SPV3.2*, an Elite Spec-Ops Commander wielding and Energy Sword and a large shield gauntlet was encountered as an enemy in the final area of Fight For The Future. In *3.3*, this particular enemy was removed, making Rtas 'Vadumee the only Elite Spec-Ops Commander seen in *SPV3*.
	+ Rtas also has a unique character model that differs from the regular Spec-Ops Commander. His eyes lack any texture and glow white, the reason for this is unknown. He has also has his left 2 mandibles removed, to match his appearances in *Halo 2* and *Halo 3*.
* Captain Keyes, Sgt Brandon and Foehammer are the only Hero Units who official die in the story.
* The fight against Chieftain Lapidus is inspired by the Tartarus boss fight in *Halo 2*.
