How to Play Cyber Stadium Series—Base Wars
Quick start
Choose Exhibition for a quick game and learn normal batting and pitching first. Press A to swing, or hold and release A while pitching for a fastball. Direct runners with the D-pad plus B to advance or A to return. When a base battle begins, attack with A or B and use special moves selectively so your robot survives later innings.
Controls
D-pad: move players, aim pitches, and select runners or bases. A: swing, pitch, attack in battle, or return/throw toward a selected base. D-pad+B: advance a runner. Hold then release A while pitching: fastball. In battles, A and B use attacks; A+B followed by A or B performs a special attack. START: pause.
Cyber Stadium Series—Base Wars — About this game
Cyber Stadium Series—Base Wars turns baseball into a contest between armed robots. Batting, pitching, fielding, base running, and season play follow a recognizable diamond-game structure, but contested bases launch one-on-one battles using each robot’s weapons. A game can be won by scoring more runs or by destroying three opposing players, while team customization and equipment purchases add a strategic layer between matches.
