Transformers: Rise of the Dark Spark is an action-adventure video game based on the Transformers toy franchise. It was developed primarily by Edge of Reality, with the Nintendo 3DS version developed by WayForward Technologies. It was published by Activision and released worldwide on June 24, 2014. It is the third installment in the War for Cybertron series and the fourth installment in the movie game series. The game was released on June 24, 2014 for Microsoft Windows, Nintendo 3DS, PlayStation 3, PlayStation 4, Wii U, Xbox 360, and Xbox One. The game serves as both a prequel to Transformers: Fall of Cybertron and the film Transformers: Age of Extinction.
The game begins in continuity with the film, wherein a mysterious purple meteor crashes into Earth. The Autobots reach the crash site and Optimus sees an ancient Cybertronian relic called the Dark Spark, the antithesis to the Matrix of Leadership. Whereas the Matrix grants wisdom, the Dark Spark gives the user the power to bend the universe and its inhabitants to their own will. The Autobots clear out the mercenaries defending the relic, but fail to stop the bounty hunter Lockdown from escaping with the relic. The perspective changes to Cybertron, where Megatron and Optimus give explanations to their factions’ current state: the Autobots face their darkest hour, where the Decepticons are near victorious.
On Cybertron and within the War for Cybertron continuity, Megatron sends Soundwave, Starscream, and Shockwave to the Crystal City vault to find the Dark Spark in order to wipe the Autobots from the face of the universe. They encounter heavy resistance from subterranean bugs. Shockwave deviates from the course as he tries to stop these bugs, where he encounters the Insecticons Hardshell, Kickback, and Sharpshot. Upon defeating them Shockwave convinces them to join the Decepticon faction. The team reaches the vault, which is guarded by ancient warriors. After defeating the warriors, the group finds that keys are needed to open the vault. Once all the keys are retrieved, the vault opens to reveal the Autobots Ironhide and Sideswipe inside, who then steal the Dark Spark. They escape through a door just before it closes and locks.
Sideswipe and Ironhide then rally with Optimus and Bumblebee at a train station. Sideswipe tries to call for a train, but it leaves before the Autobots can get onto it. While waiting for another to arrive, the Autobots have to defend themselves against a horde of Insecticons and Starscream. The next train arrives and the Autobots board it. It travels only a short distance before Shockwave detonates a bomb that destroys the train.
The Autobots emerge from the wreckage and Optimus tries to fool the Decepticons into thinking he has the Dark Spark. The Insecticon Sharpshot informs Shockwave that Ironhide is actually the one carrying it. The two give chase after Ironhide, and forcefully take the Dark Spark from him. Autobots attempt to stop them during their escape, but the two flee to the lower levels of Cybertron. There they encounter a ruin that was once used to house the Dark Spark. While Sharpshot powers up the exit door Shockwave gleans information from the computer logs. The two make it through the door, and meet up with the Combaticons who escort Shockwave to Megatron.
During the escort, Swindle and Shockwave are ambushed by Cliffjumper and a group of Autobots. Swindle eventually overpowers Cliffjumper, but the Autobot gets away before Swindle can kill him. Shockwave and Swindle then continue making their way to Megatron. They arrive at the gates of Kaon only to find it attacked by Autobots. After a lengthy battle the Combaticons combine into Bruticus and eliminate the rest of the Autobot troops. Cliffjumper tries to destroy Bruticus by planting a bomb on his back but is quickly taken captive. With Megatron having the Dark Spark, Optimus must infiltrate Kaon with Jazz to rescue Cliffjumper and destroy the Dark Spark. Their rescue is successful; Cliffjumper and Jazz escape, leaving Optimus to confront Megatron, now in control of the Dark Spark. The two battle as Megatron uses the Dark Spark (through a huge chunk of Dark Energon) to revive dead Autobots as mindless drones. The Dark Spark is expelled from Megatron’s body during the fight’s climax, hurling it into space.
The perspective returns to Earth and the film continuity, where Bumblebee and Drift work their way through canyons which lead to Lockdown’s stronghold. Drift is captured, and Bumblebee is left to rescue him. The two battle insurmountable forces, and at their most desperate moment Grimlock bursts into the stronghold and comes to their rescue. Lockdown escapes, fleeing to a second site where he intends to open a time bridge and begin the Autobot and Decepticon war anew. Grimlock, Bumblebee, Drift and Optimus work their way through the city to the entrance of Lockdown’s base. Optimus bests Lockdown in combat, and the final shard of the Dark Spark is ejected from Lockdown’s body by Drift’s sword. Optimus uses a beam from the Matrix of Leadership stored within his chest to destroy the Dark Spark shard.
In a credits scene, the Optimus Prime from the Transformers: Generation 1 continuity also sees the Dark Spark falling to Earth.
