Space Invaders II1980

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.

The object of Bosconian is to score as many points as possible by destroying enemy bases and ships. The player controls a small fighter ship that can move in eight directions and can fire both forward and backward. Each level consists of a number of green space stations that must all be destroyed to advance to the next level (a semi-transparent mini-map helps identify their location). Each station consists of six cannons arranged in a hexagon, surrounding a central core. The player must either destroy all six cannons or shoot the core to destroy a station, and in later levels the core is capable of defending itself. Additionally, the player must avoid or destroy asteroids, mines, and a variety of enemy missiles and ships that attempt to collide with the player's ship. Enemies occasionally launch formation attacks — destroying the leader causes all remaining enemies to disperse, but destroying all enemies in a formation scores extra bonus points. A spy ship (worth a random bonus value) also appears occasionally, which must be destroyed or the enemies will go berserk.

Asteroids is an arcade space shooter released in November 1979. The player controls a spaceship in an asteroid field which is periodically traversed by flying saucers. The objective of the game is to destroy both, asteroids and saucers. The triangular ship can rotate left and right, fire shots straight forward, and thrust forward. Once the ship begins moving in a direction, it will continue in that direction for a time without player intervention unless the player applies thrust in a different direction. The ship eventually comes to a stop when not thrusting. The player can also send the ship into hyperspace, causing it to disappear and reappear in a random location on the screen, at the risk of self-destructing or appearing on top of an asteroid.

Astro Wars (subtitled Invader From Space on the title screen) is a space shooter for the Super Cassette Vision.

Astro Wars II: Battle in Galaxy is the follow-up to Super Cassette Vision's previous space shooter.

The player must use a 2-way joystick to direct a cannon (this time, referred to as "Xerovy") across the bottom of the screen while using a single button to fire shots up at formations of descending invaders (this time, the regular invaders are referred to as "Flector", and the new "deflector" and "master" ones are referred to as "Legard" and "Zicon" respectively); the shields (or "barricades") are also referred to as "Xero-Guards", and the lights in them will change colour from blue to yellow to red, as they are hit, before blowing out and exploding. From the third stage onwards they will also occasionally move and try to block your shots - also, the UFOs that occasionally fly over the formations will also occasionally be carrying a powerup (the blue "Gazel", the yellow "Goral", and the red "Gowl"), which (if you do not shoot the UFO dead-centre) will fall down onto the Xerovy, and bestow its powers upon it, altering its appearance in the process. Also, if there are three or more "Zicon" left for the end of any stage, it will invoke a new "Challenging Stage" (as they fly up to the top of the screen, transform into one of three different "Mother Ships" and fly around above you while sending out eight types of "bonus" invaders).

Your assault ship was specially designed to destroy Hyperion Military Bases. Destroy as many as possible. You can fire missiles in the gaps in the Force Field or from inside the Force Field. If you are able to sneak inside, you must quickly destroy the bace before the Force Field closes on your ship. This is no easy task!
