Coppertops

Coppertops is a special encounter in Fallout Tactics. This is a play on the The Matrix movie, in which humans were essentially batteries that fueled a robot empire. Several humans (called 'Human Battery') are running on treadmills while a task-master robot oversees the entire operation. On the far side of each pair of treadmills is a locker that you can lockpick and obtain 200 Small Energy Cells (each). These energy cells are regenerated over time.
