Ketsui: Kizuna Jigoku Tachi

In a near-apocalyptic world ravaged by global warming, a global arms dealer company, EVAC Industry, is discovered to be stoking tension and triggering wars in order to boost its weapon sales. In a last act of desperation, the United Nations forms a clandestine squad of four ships to sneak into EVAC's territory to take out their private army and end the war.

Ketsui is a manic (bullet hell) shooter in the classic Cave style with a very heavy focus on scoring. The player has a choice between two ships; the slow-moving Tiger Schwert has a wide shot, while the fast-moving Panzer Jäger has a focused shot. Both ships feature a lock-on mode; by holding down the shot button, the player shoots a tightly focused laser and the player's support ships lock onto the nearest enemy, allowing the player to strafe while continuing to shoot.
