The Beast Within: A Gabriel Knight Mystery is an interactive movie point-and-click adventure game released by Sierra On-Line in 1995. Unlike its predecessor Gabriel Knight: Sins of the Fathers, released in 1993, The Beast Within was produced entirely in full motion video. The technology was popular at the time of the game's production with the recently introduced storage capabilities of CD-ROMs, but was expensive to produce. Its sequel, Gabriel Knight 3: Blood of the Sacred, Blood of the Damned used a rendered 3D engine. In 1996, Computer Gaming World magazine named it their game of the year.
