R-Type is a side scrolling shoot-em-up arcade game produced by Irem in 1987, first published by Nintendo on Arcade coin-op machines. The player controls a space fighter named the R-9 to defend humanity against a mysterious powerful alien life-form known as the Bydo. The game is made up of several sequential levels, with a boss enemy at the end of each. The player controls a small spacecraft and must navigate terrain and fight enemies using the various ship weapons. The player's spacecraft has, by default, a weak but rapid-firing main gun, which can take out waves of weak fighters; and a more powerful gun called a wave cannon, which requires the player to hold their fire to build up power for the cannon. When released, this fires a concentrated bolt of energy which can do more damage to larger enemies...
