218A longplay of Thunder Force IV.
Thunder Force IV, known in North America as Lightening Force: Quest for the Darkstar, is a 1992 side-scrolling shoot 'em up video game developed and published by Technosoft for the Sega Genesis as the fourth installment of the Thunder Force series. The game was released in Japan on July 24, 1992, in North America in September 1992 and in Europe in December 1992.
Taking place directly after Thunder Force III, the ORN Empire is thought to be defeated by the Galaxy Federation, but still suffers from increasingly frequent attacks from hostile forces. The forces are discovered to be the "Vios", an army made up of allies and residual forces of ORN. The Galaxy Federation discovers the location of their headquarters on the planet Aceria and attacks, but since the power of Vios has grown greater than the previous ORN Empire, the Galaxy Federation forces are initially defeated. Once again, they develop a new small yet powerful fighter spacecraft, the FIRE LEO-04 Rynex to eliminate Vios. The player controls Rynex and travels through ten stages while battling Vios forces.
