Enemy Exchange Program: Difference between revisions

** Blood Elf Spell Breakers can convert summoned units.

* In ''[[Starcraft]]'', the Protoss Dark Archon has a Mind Control ability that can capture enemy units and convert them to your side. If it's used on an enemy worker unit, you can then use it to build that race's units - and since the three races all have separate [[Arbitrary Headcount Limit|Arbitrary Head Count Limits]], it is then possible to raise up 200 units of each race in your attack force.

** The Zerg get an aversion though: an infested command center is acquired by beating an enemy command center to the red, then getting a Queen unit to the building before it explodes. For your trouble you get an entirely different building that makes [[Action Bomb|Infested Terrans]], a unique unit which is also far different from what a Command Center usually produces.

* In ''[[Star Craft 2]]'' there is an achievement called Zerglot. While playing as Zerg against a Protoss opponent, use an Infestor unit's mental parasite ability to take temporary control of an enemy probe, which is the Protoss worker unit. While the probe is still under your control, build a Nexus, the Protoss Command Building. Then continue building Protoss buildings with probes built at the Nexus until you can build a Zealot, and then build it. This earns the Zerglot achievement. It is possible to do this in any game mode, but playing against the AI makes it much easier. It is also possible to do this with Terran units by capturing an SCV, but it will either have to be captured again by different Infestors, or multiple ones will have to be captured sequentially to build a Command Center.

* Averted in Warlords Battlecry 2, whereas the hero can convert enemy buildings, but the buildings can not be used to build units. They add to your army limit though.

* ''[[Warhammer 40000]]: [[Dawn of War]]: Dark Crusade'' introduced the Necron Lord Destroyer, which could "possess" enemy vehicles and convert them to your side. When these vehicles are destroyed, the Lord Destroyer pops out damaged but "alive". Seeing as you could only build a maximum of two of these, though, using this is situational.

* Averted in ''[[Star Trek]] Armada'': to capture an enemy ship, it's shields must be disabled and then boarding parties must be beamed onboard, taken from the capturing ship's crew compliment. The boarding crew will invariably take casualties as well, and ships have a minimum crew requirment before they will operate at full efficiency. The Borg, however, play it straight by holding ships in a tractor beam and transporting the enemy crew ''off'' to be assimilated, though they can also capture ships the 'standard' way.

** Also played somewhat straight in that capturing an enemy construction ship allows you to access the entire tech tree and build a complete fleet of ships of the construction ship's original race. They will, however, be crewed by members of your own race, often with hilarious results such as a Romulan-manned Borg cube responding with, "Warbird reporting..." when selected because the sound bites for a given unit type (in this case "battleship") are simply transfered straight across (in this case from the Romulan Warbird to the Romulan-manned cube) to all "battleship" type units manned by your race without regard to whether they are fitting or not... Also, by the way, only the Borg's Assimilator unit transports the enemy crew off their ship to be assimilated (where they are either added to the Assimilator's crew or added to your general crew pool if the Assimilator has a full compliment) and it does not actually hold the enemy ship in place. The Borg cube's holding beam does hold enemy ships in place, but it just does exactly what the transporter does except on a larger scale (more Drones are transfered per second than with the transporter) and able to do it through enemy shields... Incidentally, capturing an Assimilator as another race does not remove its special ability. This has the hilarious side-effect of having, say, a Federation-manned Assimilator "assimilating" enemy crew, including the Borg player you stole it from in the first place.

* ''[[Warzone 2100]]'' had the NEXUS link turret, which infected enemy units with a virus that made them fight for your side. Somewhat subverted that in single player, it's mostly the enemy NEXUS faction using it on ''you'', and by the time you research the link turret yourself, NEXUS has the Resistance Circuits tech (also obtainable by the player) that makes the link turret ineffective.

* [[Real Life]]: During [[WW 2]], this was an integral part of German war strategy. On field level, German forces often captured and used enemy tanks, cars, and cannons (even horses were used). But it was also extended to larger scheme with strategical resources: Germany produced most of light tanks in Chechoslovakia, and heavy tanks were produced in France, after both lands were captured. Also additional planes were constructed in the Netherlands' existing factories, not to mention Austrian ones, which supplied antitank cannons. This explains how Germany was able to fight successfully against Allies while having much less resources.

** And earlier in history, the Ottoman Turks used [[wikipedia:Janissary|janissaries]], who were originally forces composed of captured citizens trained to fight for the Ottoman side.

** The Nazis also recruited a sizable amount of soldiers from the occupied territories. Volunteers, that is. If they hadn't been so blindingly stupid (and, you know, racist), they would have had a much easier time in the Soviet Union, where they were initially ''welcomed'' by the populace. Though they were tot necessarily volunteers. Stories exist where the 'volunteers' turned side at first sight of Allies, and about one chinese who was captured during war, taken into red army, transferred to eastern front during WWII (western from POV of soviets), captured by Nazis and transferred to Normandy where he was captured by Allies.

* ''The Elder Scrolls Oblivion'' lets you summon various daedra and other such things that would normally be enemies. But they turn on you if you attack them enough.

** In also features limited duration command spells that get enemies to fight for you.

* ''[[Machines Wired for War]]'' features allow you to take over enemy buildings as well as steal unit design plans, also the Judas warlord that can convert enemy units to your side.

* Done in ''[[Aztec Wars]]''. In fact, constructing some of your own units requires a building that can be only built by an enemy nation.
