Basewars is an NES baseball game from Ultra Games that mixes traditional diamond play with robot combat. Set in the 24th-century Cyber League, it turns pitching, hitting, fielding, and base running into a futuristic brawl between mechanical teams. Cleaned, tested, and guaranteed to play. Authentic cartridge. Baseball gameplay includes pitching, batting, fielding, and base running with an added combat system for contested bases. One-on-one battle royales decide base possession, using robot fighters armed with weapons such as laser swords and fire guns. Players can choose and name teams, set robot rosters, and earn victory money for repairs and upgrades. Upgrade options include hyper engines, ultra shoulders, iron gloves, and other mechanical advantages. Pennant race play supports leagues up to 10 games, with saved stats for league ranking, home runs, ERAs, and battle victories. The game’s World Domination Series gives its robot-baseball premise a full tournament-style goal beyond single exhibition matches.
