Hall of Fallen Heroes
From Diablo Wiki
The name has changed from "Halls of the Dead" to "Hall of Fallen Heroes", as of February, 2011.
The dead character will nottake up one of your ten live character slots. Although not much else is known, it has been confirmed that the dead characters will not be able to be taken into a game to walk around and look at. 
Hardcore was implemented in Beta Patch 14, which also debuted the Hall of Fallen Heroes.
Once a hardcore player has been slain, they will be directed to the character selection screen where a new button will appear: archive. The player may archive a fallen hardcore hero, and it will be retained in the hall, which is, as stated above, part of the player profile.
Once there, a few stats are tracked by the game client:
- Level Reached: The final level reached before death.
- Slain By: Who (or what) killed the hero.
- Damage Type: What the fatal type of damage was.
- Monsters Killed: Total number of monsters killed over the hero's lifetime.
- Achievement Points: How many points the hero had amassed before falling, although this isn't currently displayed.
There are a limited number of slots available in the hall, but the precise number is still unknown. The dead HC hero must be at least level ten before being allowed into the hall.
Making the Cut?
The Diablo III development team has been cutting features as of early 2012, presumably to meet some kind of release date that occurs before computers become sentient, making programs ironic. There was a possibility that the Halls of the Dead would not appear in the final game, per Bashiok:
However, he never mentioned the Hall of Fallen Heroes, and was perhaps being a bit sneaky, as it is currently in the game and playable by beta testers.
Diablo II Hardcore Graveyard
did not have any such feature, and dead Hardcore characters continued to occupy one of the eight slots on a Battle.net account. This forced players to delete dead characters eventually to clear our space, which could be a sentimental moment for a player.
Players went to lengths to record the existence of their Hardcore character. Fansite Diabloii.net launched a Hardcore Graveyard in mid-2000, just weeks after the game's release. It presented screenshots plus captions that shared various useful details about the tragedy:
- Character Name, Class, Level, and Realm/SP:
- Location of Death:
- Cause of Death:
- Greatest Regret:
- Famous Last Words:
- What Could Have Prevented This Tragedy:
In the years since then, players have maintained other such graveyards.
