Duality: ZF is the first video game to support DUAL PLAY natively.*
Duality: ZF is the first 2D shooter (shoot'em up, shmup) video game to support eight independently controlled fighters simultaneously.
Duality: ZF has high-action, intense, quick-reflex gameplay.
Duality: ZF has simple gameplay. Move and shoot. No bombs that blow up everything on the screen. No powerups that power you down or switch weapons against your wishes. Move and shoot. That's it. Playing is about skill of missing enemy bullets with skill of shooting enemies down. There are no complex controls or weapons to master. Move and shoot.
