Tether

You've trained for years, but your survival now hangs literally by a thread. Alone in the cold emptiness of outer space. No time for fear. No time to panic. No time to think. It's time to act!

Control your breathing... Slow your heartbeat... Collect oxygen... Avoid asteroids... Breathe...

Survival depends on the skilled use of your tether. Use it well... It's the only lifeline you have!
