R-Type is a science-fiction themed horizontally scrolling shooter franchise developed and published by Irem for arcade systems and home game platforms.
Other pieces of media, such as plastic-resin model kits, soundtrack albums and literature, were also produced.
The series centers on an intergalactic war between humans and the Bydo, a powerful extraterrestrial race that are made from both biological lifeforms and mechanical structures.
Most games have the player controlling the R-9 "Arrowhead" star vessel, although other entries have slightly altered versions of the ship instead.
R-Type video games have been released for multiple home video game consoles, as well as personal computers, handheld systems and mobile phones.
