The game Transformers: The Game follows the story of either the Autobot or Decepticon factions as they search for the AllSpark, an artifact that gave life to their race. The Autobots aim to protect it, while the Decepticons seek its power for evil. This conflict began on the planet Cybertron but was brought to Earth by the Autobots in a last-ditch attempt to keep it safe.
The game features a 3D sandbox environment where players can choose between the two teams, each with their own story-based goals and objectives. The Autobot storyline follows the plot of the original movie, while the Decepticon storyline allows for more aggressive action against their enemies. Players can select characters such as Optimus Prime or Bumblebee from the Autobots, or Megatron and Starscream from the Decepticons.
The gameplay involves switching between a robot and vehicle/aircraft form, jumping, blocking, diving underground, rolling, dodging, using various weapons, and climbing buildings. Special actions can be unlocked through the skill tracker by performing long slides or jumps, which light up symbols that provide extra abilities.
Collectibles are scattered throughout the game, including promo images, artwork, and playable versions of original "Generation 1" characters. While the gameplay is similar across all platforms, certain features are exclusive to specific versions.
