On NT3RF4C3 and VR

Good comments, thanks! I've made some corrections to the text to clarify, as follows.

- A Hacker with the ‘Interface’ asset can use an EyePad to enter a corporation’s private virtual reality network, assuming that he can first breach its security with a successful hack. These VR networks (aka MUDs, for ‘Multi-User Dimensions’) provide access to a corporation’s data stores and servers; secured computers not connected to the network can only be accessed directly. All MUDs are controlled by Virtual and Artificial Intelligences, so once a Hacker breaches a MUD, he can expect to confront the intelligence (in negotiation or combat as a creature, person, or even the environment).
Any damage that occurs to a character in the MUD may cause brain damage or death due to feedback in the character’s brain. MUDs may appear as anything the intelligence (or the original programmer) selects, such as the digital grid in TRON, the false reality in The Matrix, or a mix of themes as in Sucker Punch. The Director determines the full extent of the MUD.

The question about other users might need to be answered in a supplement - I'll have to ponder that one!
