Transformers: Dark of the Moon (marketed as Transformers: Dark of the Moon – Stealth Force Edition for Nintendo 3DS and Wii) is an Action-adventure video game which was released on June 14, 2011. The PlayStation 3 and Xbox 360 versions of the game were developed by High Moon Studios who previously developed Transformers: War for Cybertron while the Wii, Nintendo DS, and Nintendo 3DS versions were developed by Behaviour Interactive. The game features a mode known as “Stealth Force” in which characters only partially transform from their vehicle mode. Weapons protrude from the vehicle form and more precise controls are available, such as strafing, airplanes also use this Stealth Force. Electronic Arts also released mobile incarnations of the game for Symbian, iOS and BlackBerry.
In the Xbox 360 and PS3 version of the game the story begins three years after Transformers: Revenge of the Fallen. Bumblebee is sent somewhere in South America to plant Wheeljack’s virus to a Decepticon transmitter that is listen to the Autobots’ transmissions with NEST, which he does with the help of Optimus Prime and Sideswipe. Then, in Detroit, the city is attacked by Mixmaster and his Decepticon army. Ironhide is sent to destroy all Decepticons with the help of Ratchet. Ironhide kills Mixmaster with an experimental shotgun, which was given by Wheeljack. Somewhere in South America, Sideswipe disappears in the jungle so Mirage is sent to meet Bumblebee, but he encounters Starscream and is knocked out by him. Mirage wakes up to find himself in the jungle after being knocked out and does not have his ability’s to transform and use his weapons, but he does gets his abilities back after sneaking to a crashed NEST helicopter and get a supply drop containing his weaponry. He does find Sideswipe with the help of Bumblebee.
Meanwhile, Megatron orders Soundwave to go to a former Sector Seven base on an island with Laserbeak. They find knowledge of a crash on the moon during the 1960’s and an advanced technology called MechTech, which Soundwave destroys them by triggering an volcano eruption before escaping the base. Starscream is sent to Nepal to find and destroy the remaining MechTech that is about to be airlifted by Stratosphere from a NEST facility somewhere in the snowy mountain range. Then, he fights the Aerialbots, consisting of Air Raid, Breakaway and Sliverbolt. Starscream takes them out, along with Stratosphere who is carrying the technology. Starscream returns to the Decepticon base in Russia, but he doesn’t know that the Autobots put a tracker on the weapon.
The Autobots invade the base while that is happening, Megatron gets a truck mode and fights Warpath, an Autobot tank. Megatron then finds a cryotube holding a frozen Shockwave, a Decepticon assassin. Meanwhile, he fights Optimus Prime, takes him down and kicks him into a pit holding Shockwave and Driller, a worm-beast like transformer who only works under Shockwave’s command. Prime fights both of them before they flee. Optimus then claims that the battle is won, but he knows that the war is far from over. Somewhere in Africa, Megatron and the Decepticons meet and launch “Operation Pillar”.
In the 3DS and Wii the story again begins three years after the events in Transformers: Revenge of the Fallen, the Autobots continue to hunt for the Decepticons despite humanity believing that they have fled the planet, defeated. Optimus Prime, Bumblebee, and Mirage head to a desert to test out the new “Stealth Force Mode” upgrade given to them by the Autobot scientist Wheeljack. After finishing up, Optimus tries to contact N.E.S.T. headquarters, but something jams his link to them. Bumblebee is sent to infiltrate a Decepticon base also located in the desert to find out why. He discovers that the Decepticons are using satellite dishes to jam the Autobots communications. After shutting them down, Bumblebee heads inside the base to scout it out, but his link with the Autobots is lost, prompting Optimus to go in after him, blasting down the door to the base after a brief fight.
Wheeljack tasks Optimus to plant an upload virus into three satellites so the Autobots can learn the Decepticon’s motives, and ends up trying to protect them from the Decepticons. The upload is a success and Optimus ends up fighting the Decepticons for five minutes until Bumblebee escapes the base andStratosphere arrives to pick them up. The Autobots had escaped and learned that the Decepticons are plotting an attack on Detroit, Michigan and are involved in a project called “Operation: Pillar” and Megatron is interested in something or someone called “Shockwave”. In Detroit, Soundwave and the Constructicon Mixmaster lead a full-scale assault on the city, with Ironhide as the only Autobot in the area.
Soundwave deploys Lockdown to attack the Autobots and to infiltrate the base, where Lockdown targets the mainframe terminals to upload a virus created by Mixmaster. Meanwhile, Ironhide protects some satellite dishes from the Decepticons and learns that Mixmaster is trying to bring the rest of his former teammates back online and to reform Devastator. After destroying the components and killing Mixmaster, he battles Soundwave, who is being aided with aerial support from Starscream. After a brief fight, Soundwave ends up defeated and flees. Optimus calls Ironhide to return to the headquarters and enters the Autobot base Lockdown entered. Starscream tasks Lockdown with destroying the controls for the main gate and escaping, all while avoiding Optimus. He succeeds and Starscream tells him to retreat, as Megatron has new orders for him to carry out.
The Autobots track the Decepticons to an abandoned base in Siberia, where Wheeljack informs Optimus and his team that Megatron is trying to reactivate his primary objective: Shockwave, who is revealed to be a deadly Cybertronian assassin. Optimus deploys Mirage to take out the Decepticon’s communications and Ironhide to take out the shield that is protecting the base’s entrance. Upon learning of the Autobot’s presence, Megatron deploys Soundwave to hold off the Autobots while Megatron reactivates Shockwave. Soundwave ends up battling Mirage, who is being aided with aerial support from Stratosphere. Mirage ends up defeated and flees proclaiming, “You got lucky! It won’t happen again!”
Megatron destroys the coils inside the base to speed up Shockwave’s reanimation, which he succeeds in doing. Upon awakening, Shockwave tells Megatron that his energon levels are depleted, prompting Megatron to hold off the Autobots while Soundwave takes Shockwave to a safe location. After defeating multiple Autobots, Megatron learns that Shockwave’s minion, a massive Cybertronian, multi-headed, metallic, worm-like creature called “the Driller” has been awakened. Megatron tells Starscream to take the Decepticons and leave Siberia and decides to use the Driller to destroy Optimus.
Ironhide confronts Megatron as he is fleeing the base, having defeated Optimus. Against Wheeljack’s warnings, Ironhide battles Megatron and defeats him, who admires him for having “a warrior’s spirit”, and vows that when they meet again, he will crush it to dust. Wheeljack advises Ironhide to retreat and that they’ll get Megatron next time, which Ironhide swears to accomplish.
In South Africa, Megatron, Starscream, Soundwave and Shockwave meet where Megatron tells Shockwave to head to Chernobyl to search for a certain ancient Cybertronian artifact.
