Star Trek The Next Generation: Echoes from the Past is chiefly a top-down adventure game, though it also has pronounced strategy and puzzle-solving elements. It takes place in the Star Trek universe, spanning Federation space and the Romulan Neutral Zone, and centers around the appearance of the IFD (Integrated Field Derandomizer), an artifact machine of unknown origin that, as its name suggests, allows its user to reshape matter and energy. It culminates in the IFD Trials, three tests undertaken by representatives of any races that are present when the Trials are held, and failure would mean the destruction of the Federation and the enslavement of countless worlds by the Federation's enemies.
