Droidican Soldier

From KeenWiki

These robotic troopers are the Droidican Emperor's prime defense--serving to keep the Omegamatic Warp Drive technology safe. Droidican Soldiers aren't very smart though, so they need a lot of discipline. They are easily outwitted and will only attack Keen when he is close and easily visible. They are found all over Droidiccus Prime and will be a constant annoyance, they take several hits to kill and are the most commonly encountered Droidiccus.
