Character Codes
In "LEGO Indiana Jones: The Original Adventures" Indiana Jones can visit his school, Barnett College, which allows players to see collected treasures, watch video scenes and even create your own characters. The Math classroom is where players enter secret codes to easily unlock the game̵7;s variety of characters.
For example, the character of Belloq can be unlocked using CHN3YU for his desert costume, TDR197 for his jungle costume and VEO29L for his priest outfit. Indiana Jones himself has two alternate costumes as well: VJ85OS unlocks his officer costume while 4J8S4M unlocks a disguised version.
The code 3X44AA unlocks the "Extra Characters" pack that you would otherwise have to buy within the game. This pack offers Santa Claus plus several background characters from the game: a Dancing Girl, two Shanghai Hoodlums and two Grave Robbers.
Item Codes
Other codes input in the classroom unlock items or cheats that give you a huge advantage in completing the game. These cheats would otherwise be attained by purchasing them in the College̵7;s mail room or finding the right parcel item and placing it in a mailbox during a mission.
Because the game requires you to build items, fix items and dig holes, there are codes to speed up that process. The code 378RS6 speeds up digging, V83SLO unlocks fast building, and FJ59WS allows for fast fixing.
To unlock cheats that multiply the amount of studs (currency) you collect, you can enter these codes: VM4TS9 (x2), VLWEN3 (x4), V84RYS (x6), A72E1M (x8), and VI3PS8 (x10).
For invincibility, you can enter the code B83EA1. For fun, the code 4ID1N6 unlocks the "Disguises" cheat, which simply puts mustaches and glasses on every character.
