Gameplay
Red Alert was praised for its user interface, which claimed to be more developed than the competing games of its time. Players could queue commands, create unit groups that could be selected by a number key, and control numerous units at a time. The game was known to be easy to control, simple to learn and responsive to users' commands. It also featured two factions that had differing styles of play. Red Alert is also hailed as one of the first games to feature competitive online play. The single player campaign also received high praise for its detailed story line and missions, which often required the player to defeat the enemy with various sets of circumstances before continuing. Like Tiberian Dawn, the game has split routes for most missions. The objective stays the same but only the map layout differs. The single player campaign was also complemented by live action cinematic sequences that are a feature of all Command & Conquer RTS games since the original, except for Command & Conquer: Generals.
The game balance between the forces of the Allied and Soviet armies differed from other games at its time. Unlike the 'rock-paper-scissors' balancing of modern games, Red Alert required each player to use their side's strengths in order to compensate for their weaknesses. This stood in contrast to games such as Total Annihilation or Warcraft II: Tides of Darkness, in which both sides had units with similar abilities and relied instead on outnumbering or possessing a better balanced force than their opponent.
Players acquire credits to purchase structures and equipment by mining for ores and minerals (as the valuable, yet hazardous Tiberium in the regular C&C series has not yet been discovered in this timeline). Rare gems generate more credits and are faster to mine, but unlike ores, do not regenerate within the map. Players can gain more credits and increase their buying power by building more ore factories and ore trucks.
The Soviets' vehicles tend to be more durable and powerful than Allied vehicles, but are often slower moving and more expensive. The Soviets also have superior defensive capabilities against both ground attacks (Tesla coil) and air attacks (Surface to Air Missiles), but are at a disadvantage on the sea. The only offensive naval unit the Soviets have is the submarine, which cannot attack land-based targets or aircraft, so it is useless unless the opponent builds any sea units, and while it is normally invisible except when surfacing to attack, it can be detected by destroyers and gunboats. When heavily damaged, it is not able to submerge. The Soviets' secret weapon is the Iron Curtain, a device that renders a selected unit invulnerable to attacks for a short period of time. In online play and computer skirmish, they have access to two of the Allied side's infantry: the Rocket Soldier and Tanya, a commando capable of easily killing infantry and destroying structures. They also have a wide selection of air units for assault (MiG-27, Yak-7 and Mi-24 Hind) and map revelation through spy planes, and could deploy infantry by air through paratroops or by the Chinook transport helicopter (the latter only present in multiplayer). The Soviet "tank rush" was a popular strategy online, involving building many heavy tanks and overwhelming the opponent with sheer numbers.
The Allies' forces are generally cheaper, faster to build and more agile. Their minelayers can destroy enemy armor and their infantry can survive longer with good use of their Medic unit. They are at a disadvantage on land, as the Allies' strongest tank (the Medium Tank) is still weaker than the Soviets' starting tank (the Heavy Tank) and has the same speed. The Allies have only one air unit (AH-64D Apache Longbow) compared to three Soviet units and their defences against a ground assault are much weaker. On the sea, the Allies possess an advantage in naval power thanks to the Cruiser, which has the longest-ranged and most powerful surface-to-surface attack in the game, and the Destroyer, which is capable of adeptly taking on any type of unit type in the game—land, sea or air. The Allies' secret weapon is the Chronosphere, which temporarily relocates a selected unit to another part of the map. They also possess several other tools, such as stealing enemy resources, hiding their own units and structures, temporarily disabling enemies' facilities, or revealing the game map with satellite technology, thus encouraging a strategy of undermining the opponents' own plans. In online play and computer skirmish, Allied forces have access to the nuclear Missile Silo, an exclusive in the Soviets' single-player mode.
