The gameplay here is very similar to Sega’s other classic scrolling Arcade beat em up Golden Axe except it swaps the Western Fantasy setting for a 1950’s American B Movie setting. You can chose from 2 different characters and then attempt to save the world from evil alien invaders.
There are 8 different levels to complete ranging from the Streets of the USA right up to the Alien Mothership itself, each level is quite similar and involves you shooting loads of alien scum! Each character has several short range attacks such as basic kicks and punches and also a designated weapon (for example a Lighting gun although ammo for this is extremely scarce in later levels). Each character also has the option of a special attack where they can call in reinforcements if outnumbered (such as calling in a airstrike on a large number of baddies).
On occasion the action switches from standard 2d scrolling to a basic 3d shooter such as when you enter a grocery store to replenish health supplies but must first rid the store of the alien menace.
The only real downside with this game is that compared to the Arcade original it has several features missing, such as only having 2 characters to the Arcade games 3 and only 8 levels to the Arcade games 9. That aside I would have no trouble in recommending this game to any Megadrive owners especially as it is so cheap and easy to find.
