opponents' critical damaged structures can be captured with the use of engineers, allowing the player to produce units from that structure even if not part of one's own faction (i.e. if an Allied player captures a Soviet war factory, they can produce Soviet units like the Mammoth Tank). In addition to the single-player and multiplayer campaigns, Red Alert includes a map editor and the bonus software Westwood Chat. Factions The game features two factions with differing styles of play. Red Alert requires each player to use their side's strengths in order to compensate for their weaknesses, in contrast to games such as Total Annihilation or Warcraft II: Tides of Darkness, in which both sides have units with similar abilities and rely on outnumbering or possessing a better-balanced force than their opponent. The Soviets' vehicles tend to be more durable and powerful than Allied vehicles, but are usually slower-moving and more expensive. The Soviets also have superior defensive capabilities against ground attacks, with Flame Towers (guard towers outfitted with heavy flamethrowers) and weaponized Tesla coils, with the latter being able to destroy most Allied armour in 1-2 hits, although it has very high power consumption and cannot function without a sufficient and continuous supply of electricity. The Soviets' main weakness is at sea; their only offensive naval unit is the submarine (produced in the Submarine pen), which only exists to counter Allied warships and gain intelligence. It is normally invisible except when surfacing to attack when it is vulnerable to destroyers and gunboats. They also have a wide selection of air units for assault; the Yak-9 plane armed with machine guns for strafing infantry and light structures, MiG-23 strike fighter (though erroneously depicted as a MiG-29 in cut-scenes) whose missiles are suited for heavily armored vehicles and buildings, and Mi-24 Hind helicopter gunship whose YakB rotary gun is effective against light and heavy targets; the unprotected Yak-9 and MiG are designed for hit-and-run attacks as they release their payload all at once, while the armored Hind can remain in combat longer and unleashes its firepower more gradually. In addition, the Soviets also have access to periodic map revelation through spy planes, and can deploy infantry by air through paratroopers. In the latter half of the Soviet campaign (but not in multiplayer/skirmish mode), they also have access to periodic airstrikes from Badger bombers. The Soviets' secret weapon is the Iron Curtain, a
