This is an unselectable com that appears as an option in the lobby in offline mode. Trying to select it will do nothing and its icon is identical to normal Xenosentry (Formerly SpiderofMean). Guessing this will be a non-battle scarred version of Xenosentry? Why do the author of Xenosentry and @sacrificiallamb get a second backer commander retexture in addition to their armory version? Are they higher tier?
IIRC Uber liked the sacrificiallamb commander so much they asked if they could make a second version (the Armalisk) for the boxed edition exclusive.
