Far Cry 4 Cheats and Tips

After first entering the arena open the last save file with a Hex editor like HxD for example: http://hxd-hex-editor.soft32.com/
Then find the Text-string: zÂ1× or the Hex-values sequence: 7A C2 31 D7, then skip the 04 value next to it and replace the two following values with: 6C 9F
Save the file and make sure the game will load the correct one by removing the second save file (keep it somewhere else as a backup). Now enter the arena once more, pick a fight and either win or get slaughtered, it doesn't matter. Then exit the arena and the Bushman should be available.

When you reach the first cutscreen of a new game remain idle when you are instructed to explore the mansion. After approximately 10 minutes an alternate ending will start to play.
