Bittergem is an extremely rare bonus resource. When extracted and deposited into the M.U.L.E, it can provide between 1000 - 1500 Bittergem units, which is translated to bonus credits, very similarly to Gold. It is a heavy object and must be picked up and carried by hand, or via Bosco. When carrying it, a dwarf cannot do anything but throw flares / throwables, ride ziplines, and move with a 25% speed penalty (Sprinting is also disabled). It can be dropped by switching weapons or using the Laser Pointer, it can also be thrown far away by holding the [FIRE] key ("Left Mouse Click" by default) before releasing it.
The area that the crystal is buried in is dotted by small bright pink crystals and a pink glow, similar to other large resources hidden within the walls.
- In the Closed Alpha, Bittergem was colored pale yellow.
