N

The N were one of the three races dropped from the final version of Unreal 2: The Awakening along with Striders and The_Shian.

Description
The N were intended to be trans-dimensional beings that can occupy different places in space and time simultaneously. Only 3 N exist but they can be in multiple places at once, and attack with psionics (each of the three N has a different weapon).

It was also supposed to be impossible to kill an N, the idea being that when you shoot one, the weapon simply depletes the energy used to fold space and time at that particular node of the N.

No concept art was released for the N, but they were described as being "borg-like."
