- Mission Briefing
Escape Velocity is the fifth Soviet mission of Yuri's Revenge. Premier Romanov sends the Commander to head for Yuri's secret island in stopping the traitor Yuri from using Boomer Submarines in attacking the world's major cities, Soviet or Allied.
The Soviet Commander was commemorated in Moscow as a rescuer for finding Alexander Romanov, who was shot down in Morocco by the psychic traitor's gatling guns while the Soviet Premier was in his plane. Romanov and Lt. Zofia said to the veteran that Yuri was building Boomer Sub's to attack major cities. This secret island consists Boomer Submarine attackers, hidden inside a structure called the Submarine Pen and have more firepower than the Soviet Typhoon Attack Sub.
The Soviet veteran builds a military base on the island. Also from Romanov and Lt. Zofia, the new Siege Chopper is introduced and the Soviets attack. After destroying the subs, Yuri sends forces to the Moon and the Soviets followed. Although most of Yuri's forces escaped, the threat of the subs was gone.
Cutting power to Yuri's base would be a difficult objective to achieve, since all of the Bio Reactors are garrisoned, giving Yuri's base nearly 12000 power to operate.
There are 3 landing sites to build a base:
-one near 2 Oil Derricks,but near Yuri's base.
-one near a gem mine.
-farthest and resources-restricted but safest.
You must use your Siege Chopper to defend your base,their mobile artillery will make short work of the traitors. If you build enough Typhoon Attack Subs, it is time the hunters get hunted. If you capture a Tech Battle Lab near Yuri's base, you will be accessed to build some technologies (notably, Desolator).
There's a neat trick to handle the Boomer fleet, one at a time. Separate the squids and typhoon from your initial force on their own "task force". Use the squid to scout ahead on the position where Boomers are suspected. When discovered the Boomer will lock on the squid. When this happens quickly order the squid to maneuver around the Boomer to avoid the torpedo salvo, then order the Typhoon fleet to fire at the Boomer. Use the squid to lure the Boomer from targeting the Typhoon. Be advised as the intel can be sometimes inaccurate, as two Boomers can be discovered at the same time. DO NOT order the squid to directly attack the boomer.
If you manage to takeover the nearby Yuri's base (on a hill south of your base if you choose the safest emplacement) there is an unorthodox option to take over Yuri's prism head on the top of a nearby hill near the center of the island. Continuously build the Tesla reactor until there is enough space to build a barracks next to the Yuri's prism. Expect injuries and build diversions as Yuri's prism will keep on shooting. Build a sentry gun and some attack dogs near the barracks to keep off intruders then train an engineer on the new barracks to take over Yuri's prism (yes, it can be taken). Complete domination of the hill requires you to take over the nearby construction yard and another Yuri prism. Train three engineers and a pack of attack dogs. Take over the the Yard and quickly build sentry guns around it. Deploy attack dogs before the engineer so that the prism is conveniently distracted, allowing safe takeover.
Sometimes after Yuri's submarine pen is destroyed, Yuri will decide to rush all his units to your base. Yuri's infantry and vehicles can be safely dealt with by Siege choppers and bunker emplacements but the Slave miners take time due to their heavy armor. The dangerous part of this tactic is the remaining Boomer fleet that will rush and automatically aim at you, navy first. Flak force is not recommended due to the mass launching of the Boomers' SLBMs. Maneuver your remaining navy with haste as speed is the only thing that the Boomer fleet lacks.
- In physics, escape velocity is the speed at which the kinetic energy plus the gravitational potential energy of an object is zero. It is the speed needed to "break free" from the gravitational attraction of a massive body, without further propulsion.
- If the player destroys the Submarine Pen first, the mission is immediately accomplished. It may be considered a bug.
