Sega Master System / Mark III / Game Gear
Take to the skies in a combat chopper and fly solo against an entire army in this 3D coin-op conversion. Containing both first-person perspective 3D and horizontally scrolling sections, there are plenty of aerial and ground targets to blow away - but be careful out there, they're out to get you, too!
Thunderblade must have been a pretty tricky coin-op to convert, but the programmers have managed to capture it pretty successfully with this conversion. The graphics are good, the gameplay is challenging and it provides plenty of entertainment for any shoot 'em up fan.
