Tanktics was a game developed by DMA Design in 1999 for the PC. It was published by Interplay. The objective of the game is to progress through four time periods, building and controlling tanks from that period to fight the "evil black tanks" from a more advanced period. Notably, tanks are constructed by hand out of parts, which are randomly constructed by a factory (the "Part-o-Matic") in the player's base when it is provided with resources. Different parts may offer the ability to cross different terrain, offensive capabilities more suitable to current tactics, and so forth. The player's primary control is "the crane", a flying magnet (held by, for example, a pterodactyl in the first, ancient time period) which can pick up and drop single parts. A suitable pile of parts becomes a tank, which can be selected and ordered to move by the magnet. The game also has a strong puzzle bias. The magnet can also pick up boulders (e.g. for blocking off enemy routes) and sheep (which can be used to increase the factory's production rate, amongst other things), and there are various terrain types with lasting effects. For example, driving a tank through mud will make it dirty, causing them to move more slowly until you wash them. Some maps have buttons on them which can only be activated by tanks with sufficient combat experience, and it can take considerable foresight to ensure that a tank will be able to survive to that level and be able to reach the button. Dissassembling a tank will make it lose all experience. The game is very micromanagement heavy, requiring the player to spread one's attention thinly over maintaining the continually tiring sheep at the factory, tank battles, negotiation of terrain hazards such as quicksand, and tank construction. The metaphor of the 'cursor' being a flying magnet with a physical presence in the world can make moving the viewpoint between all these tasks troublesome. GAMEPLAY: -Basics There are four worlds in campaign mode: Stone Age, Medieval, Modern, and Futuristic, each containing six levels. The enemy will always be one world in technology above you, the final one being the "Evil Black Tanks" themselves. There are also a challenge and training mode, the challenge consisting of levels in which you need to do a certain task (From killing certain tanks with boulders to crushing black sheep to defending your base with tanks needing to be reassembled) in a fixed time limit. The Part-O-Matic is the only structure in the game controlled by you. It produces a set of parts, determined by the level, one by one. The speed is determined by the number of sheep on its wheel. Sheep are found randomly grazing and can be picked up by your crane and dropped on your Part-O-Matic's wheel. After an allotted amount of time, sheep will grow tired and need to be restored in the sheep dip found throughout the level, there is commonly one beside your main HQ. Once they have rested, they may be put back on the wheel. Black sheep are your sheep's enemy, as they will spread their disease to other sheep, rendering them useless. Once a sheep has been infected, you may put it in the green goo where it heals. However, once it turns completely black, there is no way to restore it to its previous state. In order to stop the sheep from getting infected at all is to kill the black sheep via boulder to the head. Sheep are fragile, and can be killed by your enemies or by accident. Sacrificing parts to your Part-O-Matic, such as enemy tank pieces, sheep, boulders, or crates, allows the Part-O-Matic to constantly reproduce from the pre-determined queue randomly set up in-game. Crates, as the main resource for you, are found all over the place and can be carried by your tanks and returned to your Part-O-Matic. One tank can hold 4 crates and sometimes crates can be difficult to get a hold of, so the default template is a lot of powerful weapons on a 4-exhaust engine placed on water-tracks. There are four main parts to make tanks in the game. The track determines what areas of terrain the tank can cross. These included wheels, tracks which can only cross basic terrain, such as stone, half-tracks, tracks which can cross desert, snow-mobiles, tracks which can cross over snow, boats, which can cross over water, and hover-crafts, tracks which can cross over anything without suffering the effects of the ground. Making tanks without tracks renders them immobile, similar to turrets. The engine determined not only how fast the tank can go, but how many weapons an individual tank can possess. Weapons weighed down a tank and made it slower, in effect a tank with a total of five engine power and three weapons would travel the same speed as a tank with a total engine power of two and no weapons. The weapons automatically shoots at enemies within its range. You can place as many weapons in a tank as it had engine power, and can not exceed a fixed height limit. You can also order tanks to attack a specific tank or area of terrain. There are over sixty weapons in-game throughout the five time periods. Finally, the radar only comes in one variety, and is needed to make the tank function. In the game, there are power-ups, collected both by being made by the Part-O-Matic and unlocked by buttons requiring a certain experience level of the tank that touches it. These buttons may also unlock certain areas or parts necessary to winning the game. Furthermore, there are boulders, movable by crane, which can be )1 Used as Part-O-Matic resource, )2 Used to attack enemies, )3 Used as walls from enemy tanks, or )4 Used to crush black sheep. Terrain There are four main types of terrain: Ground, which can be crossed by any track and can be composed of stone, grass, dirt, etc., and Snow, Desert, and Water, only crossable by their counterpart tracks. In addition, there are quicksand, which sinks tanks' tracks and any dropped objects, mud puddles, which cause tank tracks to get muddy and slow down until cleaned, lava, which burns anything that touches it until put out by water or waiting, acid, which hurts anything that touches it until taken off, and green-goo, which rests sheep and cleans off parts. Combat In combat, each part has its own health. If the health reaches zero, the part will fly off the tank, destroyed. If the tracks are destroyed, all but one engine will fall off and the tank will become immobile. If an engine is destroyed, and the remaining engines can't support the number of weapons being used, weapons will fall off until the number of weapons matches the total engine power. If the radar is destroyed or the final engine is lost, the tank will cease to function, and lose all of its experience. The tank, unless ordered otherwise, will attack the closest enemy in range of its farthest weapon. If the tank is ordered to attack a specific enemy that is out of range of some weapons, the others will attack the closest enemy within range. Enemies will obey the same rules, except when attacking the Part-O-Matic. The destination of all enemies spawned after the start of the game is your Part-O-Matic. When attacking the Part-O-Matic, enemies will ignore their surroundings. Enemies spawn at receiver points and move to your Part-O-Matic. Objectives Your main objective in campaign mode is to eliminate all enemy spawn points by first unlocking them by pressing buttons with certain level requirements, and then attacking the now exposed vulnerable center. Once all spawn points have been destroyed, all remaining tanks including those guarding points of interest will move in to attack. Once all enemy tanks have been destroyed, you will win and complete the level. If your Part-O-Matic is destroyed, you have lost. However, in the last level of each of the four worlds, your objective is to capture a transmitter from the enemy "Evil Black Tanks" that guard them, and return it to your base. In these levels, there are no enemy spawn points to destroy.
