Obstacles are types of Polygon found in Arras.io. 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 nine sides, meaning they are nonagons, while Gravel has seven, making them heptagons.

During October 2021, Obstacles were changed to resemble pumpkins. Red-brown lines split the Obstacles in similar fashion to pumpkin ribs, while a brown circle with a green hexagon inside it serves as peduncle or stem. This decorative change is seemingly layered at the top of the Obstacle and is always nonagon in shape, causing odd details when applied on Gravels.


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 visible on the minimap. Since drones are manually controlled, they will reflect and go back to the cursor

Obstacles only appear on certain Game Modes. On FFA, Squads and Open game modes, Obstacles are mostly found near to the map borders. On non-Portal and non-Open 2TDM game modes, Obstacles never appear inside Bases, and 4TDM has Obstacles locatable at the cardinal and diagonal areas outside the Pentagon Nest, seemingly grouped in those eight locations. On Portal 4TDM, Obstacles only appear on the left map, on a rather abundant count. On Portal Maze 4TDM, Obstacles generate on the right map, usually with typical numbers from other game modes.

  • Before the addition of Maze game mode variants, Obstacles served as the Arras version of Maze Walls.
  • Tanks that have long cannons that can reach inside half of an Obstacle (like the Ranger) can shoot bullets through the Obstacle, using the Rock/Gravel as a shield.
