A "Better Than Life" chip (also called "DreamChips"). An illegal cyber-data chip which provides the user a combination of artificial reality coupled with direct stimulation of different centers of the brain. Though typically designed to provide a pre-programmed fantasy, the artificial reality need not be coherent, i.e. it can provide a totally hallucinatory environment. Chips are typically designed to burn out after one use, both to prevent the users brain from overloading from the sustained stimulation, and to force the user to purchase additional chips. BTL chips are psychologically addictive and repeated, frequent use causes permanent brain damage.
