Super ZZT, also called SZZT, is the successor to ZZT, created in 1992 by Allen Pilgrim and Tim Sweeney of Epic Games (then Epic MegaGames). Like its predecessor, Super ZZT was essentially a game creation system with a few games packaged with it, which included Lost Forest, Monster Zoo, and Proving Grounds. Like ZZT, the greatest draw to its sequel was the level editor which allowed players to create their own games. Strangely, the editor itself was somewhat "hidden" by the creators, as it was necessary to add the command line parameter /e when loading Super ZZT in DOS. Some changes to this version include floor textures, new prefabricated enemies and objects, custom hint menus, and scrolling maps allowing for much larger worlds than ZZT would allow. Although Super ZZT is in many ways a vast improvement over ZZT, it never caught on with the ZZT community like the original.
A very interesting and surprising creation!
