The original R-Type arcade game is a classic horizontally scrolling shooter released by Irem in 1987, renowned for its strategic use of an indestructible “Force” pod, challenging difficulty, and H.R. Giger-inspired biomechanical art style. It was the first game to run on Irem’s 16-bit M72 arcade system board. 

Gameplay and Features

The arcade version of R-Type is a single-player game where the player pilots the R-9 “Arrowhead” starship against the hostile Bydo Empire across eight challenging stages. 

• The Force Pod: The central mechanic is a glowing, spherical, and completely indestructible companion unit. It can be attached to the front or back of the R-9 to block most enemy fire and act as a battering ram, or detached to fly freely and provide different firing angles.
• Wave Cannon: By holding the fire button, players can charge a powerful beam weapon that, when released, can pierce through multiple enemies and environmental hazards.
• Power-ups: Collecting power-up items enhances the ship’s speed and equips the Force with various laser types (e.g., anti-air, reflective, ground-crawling lasers).
• Difficulty: The game is famous for its high difficulty, which requires players to memorize enemy patterns and level layouts to succeed, rather than relying solely on fast reflexes. 

The story of the original R-Type (1987) is a dark sci-fi tale set in the year 2163. It chronicles humanity’s first desperate encounter with the Bydo Empire, a race of biomechanical, extra-dimensional organisms that threaten to assimilate or destroy all life in the galaxy. 

The Conflict

• The Threat: The Bydo are not just typical aliens; they are a “man-made nightmare” that blends biological and mechanical structures. They warp across space to invade the Solar System, possessing the ability to corrupt and control electronic weapon systems.
• The Weapon: To counter this, the Earth Defense League (or Space Corps) develops the R-9A “Arrowhead” trans-dimensional fighter.
• The Force: The R-9’s most unique weapon is the “Force,” a glowing orb that is actually an enslaved Bydo embryo. By using the Bydo’s own biological energy against them, humanity is able to pierce their dimensional defenses. 

Mission & Ending

The player’s mission is to pilot a lone R-9 through eight treacherous stages, moving through ruined bases and organic hives to reach the heart of the Bydo Empire. 

• Final Battle: The pilot eventually infiltrates the Bydo’s home dimension and destroys the Bydo Core, the source of the invasion.
• Aftermath: While the mission is a success and the R-9 survives to return to Earth, the victory is bittersweet. Lore from later games reveals that this was merely the start of a multi-generational war, and the Bydo’s origins are tied to a tragic time loop. 

The Dark Secret (Lore Expansion)

Later entries in the series (like R-Type Final and Tactics) reveal a horrifying truth: the Bydo were originally created by humans in the 26th Century as a biological “ultimate weapon”. They were banished to another dimension after turning on their creators, only to evolve and travel back in time to attack 22nd-century humanity—meaning humans are essentially fighting their own future creation.
