Robo Reactor plays from a third-person perspective where the player aims to solve puzzles to progress. This short project into developing on the Unreal Engine 4 engine has two main puzzles on one level; one simple puzzle to introduce the controls and a larger more complex one to provide challenge. For these puzzles, the player maneuver their character to hover above the puzzle "orbs" and trigger them to change state. Changing the orb state them alters the state of all adjacent orbs, forcing the player to plan their actions. When all the orbs are lit, the player can progress, but deactivating all of the orbs will end the game for the player. While the content is small, the main purpose of the project was to develop a working understanding of the Unreal Engine and its capabilities. This game features level streaming between the interior and exterior, dynamic lighting, shaders that change over play time, emissive colors, and most of the basic functionalities of the engine.  While not a main part of the gameplay, players can see particle effects, liquid rendering, and more running in the background to bring the world alive and pull it together.
