Boundary is a multiplayer FPS. A distinctive feature of the project is that the battles in it take place in space and at orbital stations. Fights are held in conditions of weightlessness or low gravity. This makes it possible to jump high, fly and rotate around its axis. The battles here are team battles, with 5 people participating on each side. The title was originally called Project Boundary, but then it was slightly renamed. It has several classes: medic, attack aircraft, sniper, support and stuff like that. In Boundary, users control heavily armed astronauts in spacesuits. They are called astrooperators here. Their costumes allow for customization. You can improve and modify weapons. There is a wide range of handles, stocks, types of ammunition, sights, and barrels. You can also customize your character’s appearance.
