Deus Ex: Invisible War -
Stay with the repairbot and send your spy drone through the tunnel. You'll find the place swarming with power-armor equipped Paladins. Send your drone repeatedly to bring them all down, including a light spider bot. The Paladins will drop rocket launchers. Pacifists who have accepted the challenge to avoid the spy drone on power-armored Paladins can walk among them undetected with the cloak. Combined with the thermal masking biomod, you will be invisible to bots as well.
