Emergency Oxygen

The Oxygen Tank is a vital item in Take On Mars. It is used to refill your suit's oxygen supply and/ or used in emergencies as reserves. It can be created as necessary (and with the proper materials) with a 3D Printer. Due to a "Broken Oxygen Tank" appearing in the Space Program mode (it can't be used, only tossed around and stored), it is suggested that an implementation of durability on this item could be possible.
