Monolith Productions announced the next title it plans to create using its LithTech 3D engine, a project that it calls its "major development project for 1999." Sanity is scheduled for release for Christmas 1999.

　　The game will not be a first-person shooter, as might be expected, but will instead employ an isometric third-person view. The game takes place in a near-future universe where players battle each other using psionic (read "psychic") abilities such as shooting fireballs or summoning creatures to come to their aid. The game will boast both single- and multiplayer components (for up to 16 people). Monolith says its combat system combines the mechanics of card-based games such as Magic the Gathering (players can collect and trade psionic talents) with the speed of your typical third-person shooter.

　　In the game, players assume the role of government agent and pyrokinetic (fire starter) Nathaniel Cain, sent after rogue Psionics who have stolen an experimental mind control device. The game's name is derived from the fact that players use up both health and sanity points when they deploy their abilities.
