The Mighty Quest for Epic Loot is a free-to-play real-time strategy video game developed by Ubisoft Montreal. The game combines castle defense and dungeon crawling mechanics, allowing players to build their own castle and to attack those built by other players in order to collect various in-game resources such as Crowns, Gold, and Gear.
The game requires U-Play, and leaves a client running even when you exit the game. The client shows as an icon in the System Tray. No idea why this is needed, or what data it is sending to Ubisoft.
