Excellent turn-based strategy game from Julian Gollop, the man behind such classic games as Rebelstar, Laser Squad and the X-Com series. An utter bargain at this price!

Official blurb: "A turn-based strategy and combat game with role-playing elements, Rebelstar Tactical Command transports players to a not-so-distant future in which Earth is ruled by an evil empire. In Rebelstar Tactical Command, the year is 2117, and Earth is under the control of the evil Arelian Empire. A band of rebels has risen to wage battle against the Arelians. Four distinct play modes include campaign, skirmish, hot-seat multiplayer and multiplayer link mode. In hot-seat multiplayer mode, a replay option lets players review the opponent's last turn. The game's RPG elements allow players to develop unique characters and relationships and control individual soldiers. The game also boasts stealth skills, a variety of weapons, and destructible environments where players can strategically use the lines of sight rules to their advantage - or to their opponent's disadvantage."
