Tatsujin Ou

Volcanic eruptions have been occurring on a deserted planet somewhere in deep space for quite some time. Then, on a fateful day, they culminated in a gigantic explosion, and a terrifying creature appeared. It is the emperor of the Gidans, thought to be defeated in the last galactic war. Now, the threat is back: the Gidans army is quickly assembled, and in a short time they dominate the galaxy again. Only a handful of refugees escape to deliver the news to the astroport. A pilot navigating the HyperFighter One aircraft is sent to stop the Gidans once and for all.

Like its predecessor, Tatsujin Ou (also known as Truxton II) is a vertically scrolling shooter. The gameplay is very similar to that of the first game: the player-controlled aircraft has three basic weapons (distinguished by the colors of corresponding power-ups) and bombs at his disposal. The rest of the power-ups are also the same as in the first game: increasing the ship's speed, the amount of bombs, and the lives of the player characters. A special power-up can also summon two wingmen to fight alongside the hero. Beside the single-player mode, the game also includes co-op multiplayer.
