Yet another legendary, genre-defining game – in an era replete with genre-defining classics - in which a single player takes control of a ship trapped in the middle of an asteroid field. A number of large, slow-moving asteroids drift randomly around the play area and must be shot by the player. When shot, the asteroids will break into a number of smaller pieces, which must also be shot until, eventually, all of the asteroids and fragments will be destroyed and the next wave begins. Asteroids introduced real-world physics to video games for the first time, with speed and inertia all adding to the player’s problems. As well as the inertia of the player’s ship – forcing the player to allow for the ship slowing down and speeding up whenever the thrust button was utilized – shot asteroids would often send fragments flying in seemingly random directions, and at varying and unpredictable speeds. As well as the ever-present asteroids, alien saucers also make a regular appearance. These move diagonally around the screen, firing at the player’s ship and must be quickly destroyed.

Crystal Castles has nine levels with four castles each, and a tenth level which features a single castle — the clearing of which ends the game. Each of the 37 trimetric-projected castles consists of a maze of hallways filled with gems and bonus objects, and also includes stairs, elevators and tunnels that the player can use as shortcuts. The three-letter initials of the player with the highest score are used to form the first level’s castle structure. When all gems in a castle have been collected, the player moves on to the next castle. The player can also skip some castles and acquire additional lives and points by using secret warps activated by making Bentley Bear jump at special locations. A trackball and “jump” button are used for controlling Bentley Bear’s motions. Gems are collected by simply walking over them, and a bonus is given upon collection of the last gem. While collecting gems, there are a number of enemies that try to stop Bentley and/or collect the gems for themselves. With two exceptions, if touched by the enemies he will lose one of his lives. Any gems collected by the enemies also result in a lower obtainable score for that screen. Likewise, if the last available gem is collected by the enemy, the player also loses the last gem bonus. Enemies can be avoided by use of the maze and its constructs, or by making Bentley jump over opponents with the jump button, in some cases also allowing him to stun them. Some types of enemies will track Bentley’s movements in certain ways, while others move at random. If Bentley is touched, he “cries out” in a distinctive manner with the use of a cartoonish word balloons. If 3 or more lives remain, he says “BYE!”; if 2 lives still remain, the quotation is “OH NO!”; if 1 life is left, it is “OUCH!”; and finally, for the last lost life (which ends the game), he says “#?!”, so as to imitate an obscenity. At the beginning of every maze, gems are worth 1 point each; this value increases by 1 for every gem Bentley picks up, to a maximum of 99. Each maze also randomly includes a hat or honey pot, which serve the dual purpose of awarding points and providing Bentley with the ability to defeat specific enemies. The hat is worth 500 points and will make Bentley invulnerable for a few seconds and allow him to eliminate Berthilda the witch, who appears in the last maze of each level. The honey pot is worth 1,000 points, and picking it up can delay the landing of a swarm of bees. Other villains present in the game include: “Nasty Trees” which become more ornery as levels progress, a ghost that will usually appear in the Hidden Spiral levels, dancing skeletons, “Gem Eaters” who Bentley Bear can defeat if he catches them while eating a gem, and also the devilish “Crystal Balls” creatures that in later levels tend to follow Bentley Bear persistently as he collects gems. The Nasty Trees and Crystal Balls can also pick up gems. Crystal Castles contains two notable easter eggs. Jumping 100 times or more in the southeast corner of level 1?1 and clearing the maze of all gems will make ATARI appear on level 1?2.[2] On level 5?4, if the player kills Berthilda and goes to the corner of the area where she was and jumps, “FXL” will appear in the southeast corner of the screen. These are the initials for Franz X. Lanzinger, a designer of Crystal Castles.

Missile Command is a 1980 arcade game by Atari, Inc. that was also licensed to Sega for European release. It is considered one of the most notable games from the Golden Age of Video Arcade Games. The plot of Missile Command is simple: the player’s six cities are being attacked by an endless hail of ballistic missiles, some of them even splitting like multiple independently targetable reentry vehicles (MIRVs), and in later levels smart bombs which can evade a less than perfectly targeted missile. As a regional commander of three anti-missile batteries, the player must defend six cities in their zone from being destroyed. The game is played by moving a crosshair across the sky background via a trackball and pressing one of three buttons to launch a counter-missile from the appropriate battery. Counter-missiles explode upon reaching the crosshair, leaving a fireball that persists for several seconds and destroys any enemy missiles that enter it. There are three batteries, each with ten missiles; a missile battery becomes useless when all its missiles are fired, or if the battery is destroyed by enemy fire. The missiles of the central battery fly to their targets at much greater speed; only these missiles can effectively kill a smart bomb at a distance. The game is staged as a series of levels of increasing difficulty; each level contains a set number of incoming enemy weapons. The weapons attack the six cities, as well as the missile batteries; being struck by an enemy weapon results in destruction of the city or missile battery. Enemy weapons are only able to destroy 3 cities during one level. A level ends if all the cities are destroyed, or when all enemy weaponry is destroyed or reaches its target. A player who runs out of missiles no longer has control over the remainder of the level. At the conclusion of a level, the player receives bonus points for any remaining cities or unused missiles. Between levels missile batteries are rebuilt and replenished; destroyed cities are rebuilt only at set point levels (usually 10 or 12K). The game inevitably ends when all six cities have been wiped out. Like most early arcade games, there is no way to “win” the game; the game just keeps going with ever faster and more prolific incoming missiles. The game, then, is just a contest in seeing how long the player can survive. On conclusion of the game, the screen displays “The End”, perhaps a poke at oncoming Nuclear Holocaust rather than the standard “Game Over” text (however, if the player is able to make the high score list, the game then prompts the player to enter his/her initials, with the “The End” sequence skipped). The game features an interesting bug: once a score of 810,000 is reached, a large number of cities are awarded (176 cities plus the continuing accrual of bonus cities) and it is possible to carry on playing for several hours. At some later stage the speed of missiles increases greatly for a few screens. On the 255th and 256th yellow screens, known as the 0x stages, the scoring increases by 256 times the base value. For good players these two 0x stages could earn over a million points. This enabled them to reach a score of approximately 2,800,000 (although only 6 digit scores were shown, so it would display 800,000) and at this point the accelerated rate would suddenly cease and the game would restart at its original (slow) speed and return to the first stage, but with the score and any saved cities retained. In this way it was possible to play this game for hours on end. Targeting crosshair: Aim your missiles quickly but carefully. Use the trackball to move the targeting crosshair to where you want the next missile to go, then press any Launch Control button to fire the missile. The missile will explode where the crosshair was positioned when the Launch Control button was pressed. Cities: There are six cities in total on the screen at one time, three on either side of the Delta Base. If one enemy missile or Smart Bomb manages to strike a city, that city will be wiped out. When all cities are destroyed, the game is over. Alpha Base: The missile base on the left side of the screen. Press the leftmost Launch Control button to launch an ABM from the Alpha Base. Delta Base: The missile base in the center of the screen. Press the middle Launch Control button to launch an ABM from the Delta Base. Omega Base: The missile base on the right side of the screen. Press the rightmost Launch Control button to launch an ABM from the Omega Base. NOTE: The Alpha and Omega Bases launch ABMs at a slower speed than the Delta Base, so you must plan further ahead when launching missiles from those bases. Defensive Missiles : The ABMs you launch to protect your cities. Each missile base contains 10 ABMs per wave. If any missile base is struck by an attack missile or smart bomb, the remaining stock of missiles for that wave are destroyed, and the missile base is rendered useless until the next wave. You receive bonus points for every ABM you have remaining at the end of each wave. Attack Missiles : Their only aim is to destroy your cities and missile bases. Every missile wave starts off with a hailstorm of attack missiles. They never deviate from their path. They may, however, turn into MIRVs. MIRV : Surprise! There is no warning when an attack missile turns into an MIRV (with multiple warheads). Think fast. Each new missile that the MIRV unleashes is carefully targeted. Killer Satellite: A mean-looking satellite that travels across the sky at a mid-level altitude and fires attack missiles. First appears in Wave 2. Bomber: A big slow-moving target that flies across the sky at a mid-level altitude, but watch out! It fires attack missiles. First appears in Wave 2. WARNING: If you destory a bomber or killer satellite before they deploy their missiles, you may see their missiles added to the downpour. An existing missile may also turn into an MIRV. Smart Bomb: Smart enough to avoid most explosion clouds from your ABMs. Your ABM must explode next to one in order to destroy it. You can also squeen it between two explosions to destroy it. First appears in Wave 5. ‘LOW’ Warning: As soon as there are only three ABMs left in a missile base, the game displays the word “LOW” underneath that base, and a warning signal sounds. Heed the warning.
