One of the most overlooked games on the Sega Genesis, yet one of the best. Mega Turrican is a run-and-gun platformer with good graphics, excellent music, and stellar gameplay. Progress through various levels while blasting enemies, collecting weapon power-ups, and jumping platforms. At the end of each level are some pretty wicked bosses that only a guy clad in a multi-million dollar robot suit could defeat. Our hero is even equipped with a grappling hook (ala Bionic Commando) that he can swing from and reach ledges that would be otherwise inaccessible, which makes for a nice little addition to gameplay.
Mega Turrican is the third in a series of Turrican games that were popular on the Commodore 64 and Amiga platforms, and though it plays a bit differently, it definitely surpasses its already great predecessors in every way. If you're looking for one of the best action games availble for the Genesis, get it.
