Thunder Force AC

Thunder Force III is a scrolling shooter game developed by Technosoft. It is the third chapter in the Thunder Force series. It was released in 1990 in Japan, Europe and the United States for the Sega Genesis. During the same year, it was retooled into an arcade game named Thunder Force AC. In 1991, Thunder Force AC was ported to the Super Nintendo Entertainment System under the title Thunder Spirits.

This game is based on the arcade port of Thunder Force III. It will include an online ranking system for the score attack modes. The "kids mode" difficulty option from the Sega Saturn version, Thunder Force GP 2, will be included with some other additions. Something unique to this Sega Ages version of the game will also be added but it is still being developed.

From the legendary game developers at Technosoft! Battle against the Vios forces and fly as RYNEX in this side-scrolling shmup that enthralled the world with its innovative ideas, beautiful pixel graphics, and a rocking soundtrack. After beating the game, unlock “STYX” Mode and jump in the cockpit of the distinguished Fire Leo-03 “STYX” from Thunder Force III. Take the STYX’s full arsenal from the previous game in this mode, but will this older model be able to survive?

Thunder Force VI is a Shoot-'Em-Up game, developed and published by Sega, which was released in Japan in 2008.
