Did you know you can do the following?
- Refill your air tank, along with suit and health at the landing craft. Just approach the back-hatch, as you would when departing from a planet, and hold your mouse so the small hand icon appears. If you just stay there, without pressing "E," your air tank will beging refilling. - It also refills your suit and health, but I have plans to change this, so don't get used to it. Health packs and suit repair kits, and perhaps a repair/health station in your ship.
- Find treasures in caves. Some caves have more than just crystals. Sometimes aliens land on planets to use them as storage facilities. You may stumble across a hidded cache of weapons, armor or other items deep inside a planet's cave system.
- Survive on hazardous planets. If you act quickly enough, you may be able to risk a little pain and difficulty in exchange for important resources. Landing on a hazardous planet is not usually advisable, but in a pinch, doing so may get you the fuel crystals or other resources you need. Just be careful you don't waste too much time down there!
