Obstacles are types of Polygon found in They are impossible to destroy, unable to move, and able to reflect any type of ammunition that bumps into them. They come in different shapes and sizes and usually spawn in clusters of about 5-10.


There are two variants of Obstacles, "Rock" for large Obstacles and "Gravel" for small Obstacles. Rocks have 9 sides, meaning they are nonagons, while Gravel has only 7, making them heptagons.


Obstacles have the interesting ability to reflect any Bullets, Drones, and Traps that collide with it, which, as intended by the developer, can allow tanks to trickshot other players.


  • Obstacles are the Arras version of Maze Walls.
  • Tanks that have long cannons that can reach inside half of the Obstacle (like the Assassin and the Hunter Branch) can shoot bullets through the Obstacle, using the Rock/Gravel as a shield.
