The Astyanax (EPROM version) — About this game
The Astyanax (EPROM version) makes the time between axe swings part of its combat. Roche’s power gauge refills while he is not attacking, allowing a stronger flaming blow after a pause. Fast weak strikes and slower charged ones therefore suit different openings. Destroyed stone pillars can supply health, a protective shield or arrowheads for the screen-wide thunder attack. Keeping an arrowhead in reserve gives the warrior an answer when the next group leaves too little space for another measured swing.
