Alien Soldier (エイリアンソルジャー) is a Mega Drive game developed by Treasure and published by Sega in 1995. It was one of the few Mega Drive games to be released in Japan and Europe, but not North America (however it was made available briefly through the Sega Channel service), and is now considered an extremely rare collectors item. It has since been re-released for the Wii's Virtual Console service, as well as being released as part of the Sega Ages Treasure Box disc for the PlayStation 2.
This is one of the few fully PAL optimized games. While running at 50Hz like other PAL releases of that time, gameplay speed and music speed have been adjusted. Forcing the game to run at 60Hz makes it play too fast.
Some minor changes to the European version of the game were made, like the removal of the catchphrase "VISUALSHOCK! SPEEDSHOCK! SOUNDSHOCK! NOW IS THE TIME TO THE 68000 HEART ON FIRE!"
