After the PC reactivates Alpha, the little brain-bot will let the PC know that his right laser-gun arm and left maintenance arm are damaged. He will ask the player for help to repair the damage. The PC may get the spare parts off the disabled Beta and Delta bots in the hall. Then, using the advanced tool kit in the Maintenance Room, replace Alpha's damaged arms with a good arm from one of the bots. Repairing an arm takes 10 minutes of in-game time.
