Robin Hood: Defender of the Crown Cheat Codes for XBox

Unlock extras
You can unlock good weapons and items if you personally storm a castle.

Legendary items
Take over a Lord's castle personally to get one of four random legendary items. They are a bow that can penetrate a knight's shield; a lance that improves your chances at jousting; a disease option for sieges that slows enemies; and the Lion's sword which gives you more extensive and damaging sword combos.
