A Zipline Gate is an obstruction found on Zipline Cables on SkyTown, Elysia. Samus encounters them in Zipline Station Alpha, Transit Hub and Zipline Station Charlie. They are small objects resembling windows that hang along Zipline Cables and can knock Samus off of the Zipline. To avoid this, she must shoot them before she collides with them. Shooting Zipline Gates either opens them or, if enough force is used, knocks them off the Zipline. The first gate in Zipline Station Alpha can be scanned from the ledge and shot, but it quickly closes. Zipline Station Alpha has five gates, Transit Hub has two and Zipline Station Charlie has four. The number of gates on a Zipline is determined by the length of the Zipline, and whether other obstacles are present, such as Floating objects or ZipNMEBombers. The Charlie Zipline is destroyed by Aerial Repair Drones, taking with it its Zipline Gates.
