Legends: the Cancelled loot Shooter-RPG by the original Battlefront team (Patreon)

Legends is a cancelled third person action RPG planned to be released on Xbox 360, which was in development in 2006 / 2007 by the original Battlefront team at Pandemic Studios. The game would have merged cover-based third person shooting in a series of floating sci-fi islands, with usable vehicles for combat and exploration, randomized dungeons and rare loot ala Diablo plus a quest system somehow similar to what at the time was used in MMORPG such as World of Warcraft. You can imagine Legends as a lost precursor of Borderlands (which was later published in 2009), taking the classic RPG loot formula into a more action-oriented shooter:  https://www.unseen64.net/2018/04/19/legends-pandemic-studios-xbox-360-cancelled/
