The gameplay of Pandora Tomorrow is largely unchanged from the original Splinter Cell. The game features some moderate graphical improvements, as well as minor gameplay changes such as the fact that health kits are no longer an inventory item, and the addition of a laser sight to Sams pistol that allows the player to know exactly where the rounds will strike, even when moving around. Also, Sam can now open doors while carrying a body, shoot while hanging upside down, SWAT turn past doorways unnoticed, and perform a half split jump. The pistol laser was replaced with an OCP and the SWAT turn was removed in Chaos Theory, the next entry in the series. The PlayStation 2 and Gamecube versions also feature an additional single player mission to compensate for the abridged gameplay compared to the PC and Xbox versions.
