Heroic

"Your enemies are as numerous as they are ferocious; their attacks are devastating. Survival is not guaranteed."

- Description from Halo: Combat Evolved and Halo 2.

"Fight against formidable foes that will truly test your skill and wits; this is the way Halo is meant to be played."

- Description from Halo 3 and Halo 3: ODST.

Heroic is the second hardest difficulty in the Halo series campaign mode.

Summary
The symbol for the Heroic difficulty setting is represented with a shield that has the Marathon Logo encrusted into the center; over the shield are two UNSC Standard Issue Combat Knives crossed over each other.

Heroic pits and throws you against the Covenant, who are now slightly smarter, and their weapons inflict more damage per hit than their Normal-level counterparts. Even the weakest of infantry, the Grunts, take quite a few bullets until they go down. It is otherwise considered "Hard", in other games.

The following are a list of changes in the Heroic difficulty:
 * Health meter is smaller. Hits do more damage.
 * Shields are only 75% their "Normal" capacity.
 * Increased Shields and/or armor for enemies.
 * Many Minor Elites are replaced by Major Elites. Major Grunts are more frequent as well, along with other opponents.
 * Enemies are smarter in tactical actions, thus harder to kill (ex. starting to hide behind barriers when their shields are down).
 * Marines have reduced effectiveness and are weaker; their tactical intelligence has also been reduced.
 * Ultra Elites and Ultra Grunts appear ever so often and for the Elites, they normally dual wield. Zealots also begin to take the place of Ultras.
 * Many more Jackal snipers are placed throughout levels, and in Halo 3, some of them have Beam Rifles instead of Carbines.

All of these wrap up into a nice gameplay option for more experienced players, who find Normal less exciting, and Legendary too hard. This difficulty may be deemed the most realistic by some players; however, this is not to be stated as a fact, as each player has their own comfort zone, regarding difficulty.

In Halo 3, Heroic was intended for those who have played the prior games, and multiplayer, resulting in an increased skill amount. This increase means that those who found Normal comfortable in Halo 2, will find Heroic just right for Halo 3, according to Frankie. Martin O'Donnell stated that, 'Normal is for beginners who are embarrassed to pick Easy. Heroic is what we intended.'
