True Lies is a top-view action shooting game based on the 1994 film of the same title that was developed by Beam Software and published by Acclaim Entertainment.

The player controls Harry Tasker, who is tasked with the duty of foiling the terrorist plot of Salim Abu Aziz. Each stage has a particular series of goals that the player must fulfill before reaching the stage's goal. Harry's abilities includes the ability to keep his aim steady at one direction while shooting and a diving shoulder roll move that allows him to avoid enemy fire. The player has a health gauge and a limited amount of lives, with power-ups available that restore health. In addition to enemies, there are also civilians that the player must not harm during shoot-outs. If the player kills three civilians in the same stage, he will be forced to restart the current stage at the cost of one life.

Harry starts each stage wielding only a single-shot pistol that has unlimited ammo, but must be reloaded after every 15 shots. In each stage Harry can procure three additional firearms (an Uzi machine gun, a shotgun, and a flamethrower that takes the pistol's spot upon being equipped), as well as hand grenades and anti-personnel mines, which he can switch between at any point. Unlike the pistol, Harry's other weapons have limited ammunition (with a different maximum capacity) and individual ammo for each must be found if Harry runs out.
