Breach is a turn-based tactical strategy game developed by Omnitrend Software and released in 1987 for DOS, Amiga, Atari ST/STE, and Macintosh. Players command a squad of soldiers through grid-based combat missions, managing unit movement, weapon selection, and positioning across a variety of scenarios. As the first entry in the Breach series, it established the franchise's foundational approach to small-unit tactics, emphasizing careful planning and resource management over fast-paced action. The game draws on science fiction military themes, placing squads in hostile environments where tactical decision-making determines success or failure. Each unit possesses distinct capabilities, and the turn-based structure allows players to deliberate over each action. Breach was notable for its time as an early example of detailed squad-level tactical gameplay on personal computers, laying the groundwork for the subsequent entries in the series.
