Red Dead Redemption

Red Dead Redemption is an open world Western game, and the sequel to Red Dead Revolver. You play as gunslinger John Marston, sent by the US Government to kill his former outlaw friends, at the expense of saving his family.

'Dead' Horse
An unused mount exists in the game, and it's rather... gory. The horse is missing its lower jaw, has claw marks all over its body, and is missing half of its front left leg. The horse appears in the mission Spare the Love, Spoil the Child, however it obviously can't be used as it's already dead.

With save file modding however, the horse can be hacked in to replace John's current steed. The horse also boasts unlimited stamina and a surprising amount of health.

Interestingly, shooting the 'missing' part of the horse's front leg still makes it bleed.

Norra Hawkins
An unused NPC called Norra Hawkins exists in the game. She's often found stranded in The Great Plains and calls Marston over for help. It turns out she lost her dog, and he must help her find it. The dog can be found in the caves in Tall Trees. Marston returns the dog to her and receives 50 rounds of revolver ammo and the Double-action Revolver.

However, Norra often spawns already dead, so this side quest never activates unless modded in by a save file.

Wanted Posters
One of several non-mission-based activities in the Single Player campaign is bounty hunting. There are 45 bounty targets available in the released game, but apparently there were supposed to be many more. Found embedded on the game disc are numerous wanted posters that never made it into the game itself.

Dutch's Gang
Of the 45 bounty targets in the released game, only two are members of Dutch's Gang. Five other members were going to be included, but were apparently scrapped. Enepay and Kosumi are very visibly gunned down by Marston in the opening cutscene for the mission "For Purely Scientific Purposes" which might explain their exclusion.



Mexicans
This lone Mexican has a wanted poster, but was never included in the bounty targets for the released game. Judging by his attire, he looks to be a Federale which might have gotten him excluded based on the fact that lawman really shouldn't be bounty targets.



Unknown Outlaws
Several unnamed outlaws have posters embedded on the disc as well, none of them are bounty targets in the released game. The first from the left actually appears in the opening cutscene for the mission "Hanging Bonnie MacFarlane" and he has lines, but even the voice actor credit goes to 'Outlaw on Horse' so he is never named. The second from the left is actually a member of Bill Williamson's gang, and also happens to be the man who shoots Marston at the gates of Fort Mercer at the very beginning of the game. Despite this, he is never named.



For the Multiplayer characters in the game, Rockstar just re-used skins for NPCs in the Single Player campaign and gave them different names. This next character appears in the roster of Multiplayer characters as The Tudisco Kid, but he does not appear to have a Single Player counterpart. As such, his wanted poster bears no name at all.



And not a single thing is known about this last outlaw other than he was supposed to be a bounty target at some point.



Alternate Versions
These next two posters are for bounty targets that are actually part of the 45 in the released game, but for some reason have alternate versions of their posters embedded on the game disc. Oddly, the poster for Slink Bradshaw that was unused actually has a picture of the character on the poster, while the one used in-game has a picture more resembling Bill Williamson.



Miscellaneous
There are also wanted posters for both John Marston and Abraham Reyes embedded on the disc as well. These do not appear anywhere in-game.



Missing Person Poster
Even the Red Dead Redemption DLC Undead Nightmare got into the act with it's Missing Persons activity. This was similar to the bounty hunting missions in the main game, except the people on the posters had to be rescued from attacking zombies and returned to their families located in the safe zones of either Fort Mercer or El Presidio. There are 16 missing souls in the official release, but the game disc has 17 posters.

The character, Lloyd Duffy, is actually included in an official Rockstar Games screenshot depicting the activity but was ultimately cut from the roster. In the main game, Duffy refers to the fact that he has "no friends, and no family" which might have been what got him cut since there would be no one to "miss" him enough to make the poster.
