Thunder Force AC1990

R-Type Leo is a horizontally scrolling shooter arcade game. It is a spin-off of the R-Type series and the last entry to be released in Arcades. R-Type Leo was initially an original shoot 'em up game in development by Nanao before Irem retooled it into an R-Type project instead. It is also the first R-Type game to feature simultaneous two player gameplay.

After the space pilot Vanessa Gaiden defeated the Evil Empire in the events of the game Last Hope, she got missing on her way back and wasn't heard of anymore. Vanessa's husband, Gordian Gaiden, sets out to search for her. Meanwhile, a new evil has appeared in the galaxy: a planet lord called "The Master", who can create and control evil beings made of steel, and uses his power to terrorize the galaxy. On his search, Gordian comes across the evil presence of The Master and sets out in his Gunlord suit for the planet Kairos II.

The Fantasy Zone is a solar system consisting of eight brightly colored, fantastic planets. The evil Menons are trying to take over all of the planets in the Fantasy Zone by using misappropriated foreign currency to build their forces. It is the player's job to recover all of the coins and save the solar system! Fantasy Zone is an arcade style shooter for one or two players. The goal is to destroy all of the creatures on each planet and collect as many of the lost coins as possible. At the end of each level is a large enemy that will have to be defeated before moving on to the next world. At various points in the game, the player will be able to find a parts shop, which allows purchasing improvements for his spaceship, including better weapons and faster engines.

The game is the sequel to R-Type, which was first released as an arcade game in 1987 and profoundly influenced later shooting games with its charge shots, unique weaponry, and grotesque enemies. Hudson Soft ported the later 4 levels of the original R-Type to the PC Engine with the title R-Type II, but the Hudson release is unrelated to the game described in this article. The player controls a ship called the R-9C (or R-9 Custom), which is an improved version of its predecessor game's ship; the R-9. The ship's design was changed slightly, and the wave cannon was given homing capabilities. Two new types of weapons (the Search Laser and Shotgun Laser) were added, bringing the total number of weapon types up to five. A new anti-ground unit bomb was also added to the missile inventory. Though the number of levels was decreased from the prequel, the number of enemies, their durability, and the number of bullets they shoot were greatly increased. Enemy movements and terrain were also made trickier, bringing the game's difficulty up considerably. The same revival system is used as in the prequel, where the player is brought back to a checkpoint whenever their ship is destroyed. The controls are mostly unchanged from R-Type, where the 8-way joystick controls the ship's movement, and the shot button fires the ship's main beam. The other button is used to equip or unequip Force; the series' most unusual innovation. Pressing down the shot button causes the blue beam gauge to fill up, and releasing the button causes a wave beam to travel a certain distance depending on the length of time the button was pressed down. If the button is pressed down until the blue gauge is fully charged, a red gauge appears and fills up quickly. Filling up the red gauge causes it to flash blue and red, releasing the shot button at this point shoots an even more powerful beam. Unlike the normal beam that only travels in a straight line, the newly added Shotgun Laser beam explodes in multiple directions after traveling a short distance. This shot causes heavy damage if the player can target a single enemy with it. However, holding the button down after the gauge is flashing causes the beam to return to the normal transverse beam (the gauge alternates between flashing and returning to the normal state while the button is held down), so the player must release the button at the right timing in order to successfully target enemies. The other newly added beam, the Search Laser, is semi-homing, and can bend at angles up to 45°.

R-Type is set in the 22nd century, and the player flies a futuristic fighter craft called the R-9a "Arrowhead", named for its shape, and because it is the ninth model in the 'R' series of fighter craft (but it is the first of the series to actually be used in combat; the previous models were all prototypes). The mission is to 'blast off and strike the evil Bydo Empire'. The R- in the series title originally stood for "ray", as in a ray of light. It was a reference to the many different types of ray-like weapons in the first R-Type. his was later retconned in R-Type Final to refer specifically to the production code as well as a term of endearment for the player fighter craft, the "Round Canopy". The original R-Type was well received by most gaming critics. However, it was also infamous for its relentless difficulty. It earned 7th place in IGN's Top 10 most difficult games to beat. The gameplay of R-Type is noticeably distinct among shoot 'em ups. Invariably the player will lose, not because of an inequality in firepower, but because of the design of the levels themselves. There is usually a 'correct' way to get through a level, but players must learn these by experience - i.e. by losing and restarting from earlier in the level. The game innovated with its weapon system compared to contemporary shooters, featuring a chargeable shot (beam-meter), and detachable 'force' pod; levels were designed to require different tactics and ideal weapons (air-air, diagonal, or air-ground laser).

Shoot'em ups don't come any weirder than Parodius - dodge through waves of killer penguins, neon rabbits and 50ft tall dancing girls. An intense experience of one or two players. This compilation collects the first two arcade incarnations of Konami's shoot'em'up parody series on one disc: Fantastic Journey (Gokujou Parodius) and Parodius (Parodius Da!). Unlike the ports seen on the SNES these are much more accurate to the original arcade version.

The objective of Galaga is to score as many points as possible by destroying insect-like enemies. The player controls a starfighter that can move left and right along the bottom of the playfield. Enemies swarm in groups in a formation near the top of the screen, and then begin flying down toward the player, firing bombs at the fighter. The game ends when the player's last fighter is lost, either by colliding with an enemy or one of its bullets, or by being captured. Galaga introduces a number of new features over its predecessor, Galaxian. Among these is the ability to fire more than one bullet at a time, a count of the player's "hit/miss ratio" at the end of the game, and a bonus "Challenging Stage" that occurs every few levels, in which a series of enemies fly onto and out of the screen in set patterns without firing at the player's ship or trying to crash into it. These stages award a large point bonus if the player manages to destroy every enemy. Another gameplay feature new to Galaga is the ability for enemies to capture the player's fighter. While the player is in control of just one fighter, a "boss Galaga" (which takes two shots to kill) periodically attempts to capture the fighter using a tractor beam. If successful, the fighter joins the enemy formation. If the player has more lives remaining, play resumes with a new fighter. The captured fighter flies down with the enemy that captured it, firing upon the player just like normal enemies, and can be shot and destroyed. The player can free the fighter by destroying the boss Galaga while in flight, causing the captured fighter to link up with the player's current fighter, doubling his or her firepower but also making a target twice as large. Galaga has an exploitable bug that can cause the attackers to stop firing bullets at the player, due to a coding error. In addition, similar to the famous "Split-Screen bug" in Pac-Man, a bug exists in Galaga in which the game "rolls over" from Level 255 to Level 0. Depending on the difficulty setting of the machine, this can cause the game to stall, requiring that the machine be reset or power-cycled in order to start a new game.
