Supremacy: Your Will Be Done, released as Overlord in the United States, is a strategy video game designed by David Perry and Nick Bruty and produced by Probe Software. The game was initially released for the Amiga and Atari ST computers in the beginning of 1990 and later in the same year it was ported to the Commodore 64 too, but released only in the very beginning of 1991. Nearly one year later in late 1991 the game was ported to MS-DOS. The game was ported to the Nintendo Entertainment System in 1993. The NES cartridge has an internal battery to retain game saves; the computer versions came on two disks. The NES version was among the last titles released for the platform and is relatively rare. A Famicom version was planned to be released around late 1993, early 1994 by Altron however for unknown reasons it was cancelled. Gameplay The goal of Supremacy is to create and protect a network of planetary colonies and defeat a computer adversary who is trying to do the same. There are four skill levels, each represented by an enemy race, and each featuring a progressively stronger opponent. The more advanced a system is, the more freedom a player has when purchasing spacecraft. Higher skill levels result in different numbers of planets in each system. The game is controlled using a mouse pointer and important information is displayed in a message box at the bottom of most screens. Following the introduction screen, the player chooses which planetary system to enter. Planetary systems differ the types of spacecraft and equipment that can be purchased, in the number of planets they contain and the strength and aggressiveness of the artificial intelligence. The first system contains eight worlds and allows access to only the most basic equipment. The second system has sixteen planets and slightly better equipment. The remaining systems increase in size and strength similarly. The player and their opponent both begin with control over a single colonized planet in the chosen system. All other planets in between are uninhabited and up for grabs. The player must set up and maintain thriving colonies on as many planets as possible, while building up an industry and military strong enough to fend off the opponent. Because of the randomness of a system's initial make-up, the order in which planets are colonized has a great subsequent effect upon gameplay.
