Most experienced people know of Treasure, the game company that brought us Radiant Silvergun, Dynamite Headdy, Gunstar Heroes, Ikagura, Wario World, Mischief Makers, the list goes on. They are somewhat of a legendary companies for hardcore gamers. Yet their game barely crosses the obscure when speaking of titles such as Alien Soldier, an action-packed side-scrolling with speed that rivals even the Contra series itself with its persistent tension, the game is notoriously one of the hardest game on the Genesis and could best be described as one hour of boss rush with intermissions. There is little recycled content, each 25 stages unique and lasting only less than one minute each, save for the final boss. Alien Soldier ranks as one of my favorite exclusive on the system
