Thunder Force V - Perfect System [TechnoSoft Collection 2500] Japan

Genesis owners who remember the first three Thunder Force games may wonder what happened to the fourth (and last 16-bit) title in the series. Here in the states, the game was (for reasons unknown) called Lightning Force. Now, the fifth game in the series hits the PlayStation. Just like in the four previous games, Thunder Force V: Perfect System is a side-scrolling shooter in the tradition of R-Type and Gradius.
