XL Sensor Arch

The XL Sensor Arch is a large automation and interaction structure used as a sensor-based utility object in Astroneer. It can be placed as part of larger builds and works with other recreational or event setups, making it useful both for gameplay contraptions and for custom course design.

It can be used with the Recreational Sphere as another kind of goal, similar to the XL Sensor Canopy. It also works well as a checkpoint for races, since its reaction slots can be used to trigger lights or fireworks.

• It has three Tier-2 attachment slots and three Tier-1 reaction slots.
• It can be connected to Tethers to provide the player with Oxygen and Power if an Oxygenator is connected through the network.
• Before Automation Update 002, it was named the XL Sensor Platform.
