King Arthur: Knights Tale mixes an XCOM-style turn-based battle system with traditional RPG mechanics, including character development, choices that impact the direction of your campaign, and upgrading your home base of Camelot. The story follows Sir Mordred, who travels with a band of knights across Avalon in search of King Arthur. This is already an interesting twist on the classic legend, as Sir Mordred is King Arthur's nemesis, traditionally shown as the king's traitorous nephew. In this version of the tale, Mordred has actually mortally wounded Arthur, and is now stalking him through the isle of Avalon to finish the job on command of The Lady of the Lake.
