ZZT is a action/puzzler created by Epic Games. Running entirely in text mode, it is basically their answer to Apogee's Kingdom Of Kroz series. It consists of three games (or rather, three scenarios for the same game), as well as the sequel Super ZZT, which is essentially the same but in a scrolling lower-resolution screen with a few extra objects. A ZZT fan named Gregory Janson later released Mega Zeux, a Spiritual Sequel to ZZT that massively improves on the extensibility of ZZT's engine.
