You can shoot on the ground, you can shoot in the air, with this week's new Wii Virtual Console re-releases you can shoot just about anywhere…as long as it's at an alien menace.

From two of Sega's most popular consoles come the side-scrolling shooter goodness of the psychedelic Fantasy Zone and the Metroid-like Mega Turrican. Both titles let you blow lots of stuff up but while Mega Turrican features a dark and mechanical world where you go on ground patrol, zapping enemies with high tech handheld weaponry, Fantasy Zone features child-like trippy graphics and bright colors as kill your enemies from a spaceship (ain't that cute!)

• Fantasy Zone – Original Release: 1986, Platform: SEGA Master System
  The fantastical world of Fantasy Zone may look like something out of a 70s children's show, and features a space ship called the Opa-Opa, but don't let that fool you, this game means some serious business. As you command your ship while dropping bombs on enemy basses and shooting out your enemies, you'll reach several bizarre boss battles that have to be seen to believe.

• Mega Turrican – Original Release: 1994, Platform: SEGA Genesis
  The third sequel in the Turrican series of super-soldier shooters, has you as the lone survivor of the United Freedom Force, whose sworn duty is to free the enslaved galaxy from the evil rule of The Machine. Your super-suit, explosive weapons and acrobatics, make this platforming shooter highly reminiscent of Metroid, but addictive and fun nevertheless.
