Megadon
Megadon is an action arcade game developed by Epos Corporation under a Photar Industries license in 1982. The player controls a spacecraft navigating through space environments, shooting enemies and obstacles while avoiding incoming fire. The game features progressive difficulty across multiple levels, with enemies becoming faster and more aggressive as the player advances. Players use joystick controls to move their ship in eight directions and a fire button to shoot projectiles. The objective is to survive each wave of attacks and clear stages to progress further.
