Xexex is a 1991 side-scrolling shoot 'em up arcade game by Konami. It draws on Irem's R-Type and Konami's other shoot 'em up Gradius, while adding the tentacle mechanics of Irem's other shoot 'em up X-Multiply. The gameplay is similar to R-Type and X-Multiply. The player's ship, the Flintlock, has a detachable orb attachment called the Flint, which behaves similar to R-Type's Force Device. Powerups can be obtained in the Japanese version to increase the Flint's power, movement speed, change the main weapon, or even give the player an extra life. There are different gameplay mechanics between the original Japanese release and the overseas releases. The overseas versions introduce a variety of changes, with the most notable being the removal of all but one upgradable weapon. The enemy patterns are also changed slightly. In the Japanese version, the player starts with the Proton Laser, a thin stream of weak bullets. Defeating certain enemies will drop other weapons. The name of the current weapon is displayed at the bottom of the screen. In the overseas versions, the only available weapon is the Proton Laser; picking up power-ups increases the spread of the weapon. Missiles are a secondary weapon.
