The PC may avoid this conflict if he first observes the brain-bots' patrol pattern. There is a window of opportunity for the player to safely run into the Maintenance Room adjacent to the Medical Facility. Inside the Maintenance Room, the player will find a computer terminal that is directly tied into the brain-bots. A bit of hacking will get the PC into the brain-bots' command routines, where the PC may opt to disable the brain-bots.
Character type completion breakdown
Combat Boy - If he's got the Science skills, then go for it – it'll wield a bit more XP than just shooting them.
Diplomacy Boy - Ditto – can't reason with the brain-bots.
Science Boy - Time to shine. Use those Science skills to disable the bots without bloodshed.
Stealth Boy - Will make sneaking past the robotic critters a bit easier and not have to rely so much on observing their patrol pattern.
