Rust Spaceport: Red Card and Launch Site route
For the classic red puzzle at Launch Site, prepare green and red keycards, two working fuses, radiation protection, water, and healing. First, power up the two external points, then open the red door of the main building.

Two power outlets → red door → roof → exit
First external power source
Find the building with the green card reader. Follow the green card, insert a regular fuse into the slot, and turn on the power. Before crossing, check for the Bradley Patrol.
All steps listed:
- First external power source
Find the building with the green card reader. Follow the green card, insert a regular fuse into the slot, and turn on the power. Before crossing, check for the Bradley Patrol.
- Turn on the second external tool.
Get to the second power block, install the second regular fuse, and activate the switch. Do not confuse them with the Heavy Fuses at the power plant.
- Open the main building.
Use the red card at the requested reader. If the path is blocked by a destructible barrier, one card is not enough. If the reader is inactive, check both external blocks.
- Chase the loot.
Advance through the internal staircases, considering scientists, players, and radiation. Hazmat suit doesn't allow you to stay upstairs indefinitely: keep an eye on your health, water, and healing.
- Follow your route.
Leave the healing on the descent and check the exit points inside the building. Do not plan to jump from the roof as the main way to escape.
Preparation and Hazards
Bradley patrols the launch site, there are scientists inside the main building, and radiation is dangerous. One set of gear does not replace water and healing supplies. Starting from September 2026, access to rooms with a red card may be blocked by a destructible barrier: make sure to check the path in advance and prepare demolition tools.
Classic Red Puzzle
- Find the external power source for the green door: use the green card, install the fuse, and turn on the switch.
- Get to the second external power source, install the second fuse, and turn it on. Keep an eye on Bradley's route between the buildings.
- Return to the main building and use the red keycard on the locked door. If the card reader is not working, double-check both fuses and switches.
- Climb the inner stairs and check your health and radiation. Loot crates without using up all your supplies on the climb.
- Descend along the verified route and use the internal exit elements. Do not rely on jumping from the roof as the primary way to escape.
New rooms and events
In August 2026, a Satellite Event Terminal appeared at Launch Site, and in October, an additional Powergrid Loot Room was added. This room opens based on the power level of the electrical grid, which is activated at the Power Plant using Heavy Fuses. This is a separate task: the heavy fuses of the power station do not replace the two regular fuses for the classic red puzzle.
Why isn't the door opening
- The map is worn out or the wrong color is selected.
- The fuse has blown, or one of the switches is not installed or turned off.
- The puzzle has already been completed and has not reset yet.
- The server uses a modified map or custom monument settings.
