'''''Adventure Construction Set''''' (''ACS'') is a [[game creation system]] written by Stuart Smith that is used to construct [[Tile-based video game|tile-based]] graphical [[adventure game]]s. ''ACS'' was published by [[Electronic Arts]] in 1984 for the [[Commodore 64]], then for the [[Apple II]], [[Amiga]], and [[MS-DOS]]. Smith previously developed several commercial adventure games of a similar style, such as ''[[Ali Baba and the Forty Thieves (video game)|Ali Baba and the Forty Thieves]]'' (1981).

''ACS'' provides a graphical editor for the construction of maps, placement of creatures and items, and menu-based scripting to control game logic. A constructed game is stored on its own disk which can be copied and shared with friends; games exported from the Amiga version still require ACS to play.  A complete game is included: ''Rivers of Light'', based on the ''[[Epic of Gilgamesh]]''. The [[Amiga]] version has an additional pre-made adventure called "Galactic Agent" by [[Ken St. Andre]].
