Battle Forge

This product comes from Highwaygames.com

Battle Forge is a ticket redemption machine from Universal Space. Players shoot coins onto the playfield, with the machine detecting the velocity and direction of the coin and translating this into play.

On stage one, players shoot coins to stave off attacking skeletons. Once the skeletons are destroyed, players get to take on the Skeleton boss, where players must identify his weak spots and keep hitting until he is defeated.
