At
longestnight after the Borg were summoned in the first plot of the game, Boimler was partially assimilated by Borg nanoprobes before his game-based special healing killed them off, leaving him with a few permanent implants. The hand implants on his right hand look similar to
Seven of Nine's and thread all the way up to his elbow. He has none on his left.
As he's CRAU he still currently has these implants in
anaplasia.
