Add a new subrule to “The Lines”, titled “Features”:

There are certain Features which change the way that a new Grid is generated. When the Gridmaster adds a Feature to the Grid, they carry out the instructions in that Feature, performing any random selections secretly randomly. The list of all Features is as follows:
**Energized**: Randomly select 5 Cells and set their Value to Battery.
**High-Security**: Select 3 random columns or rows in the Grid, and set the Value of all their Cells to Firewall. Then, select two random Cells from each of the rows or columns selected in the previous step and set their Values to “-”.
**Warped**: Set the Location of all Live Runners to a random Cell, and inform each of them of their new Location.
**Database**: Repeat the following 5 times: Select a Disk at random and add a new instance of it to the Heap in a random cell.

Append two new bullet points to the Initialise atomic action in “The Lines”:

*Repeat the following DICE4 times: Select a random Feature and add it to the Grid.
*Post a blog entry announcing the new Grid’s Features

In the rule “Running”, replace “unless there is not a Cell in that direction from that Runner’s Location” with “unless there is not a Cell in that direction from that Runner’s Location or the Cell in that direction has a Value of Firewall”.

If the Proposal “I’m afraid it’s terminal” was enacted, add a new Feature to the list in “Features”:

**Access Point**: Set the Value of the Cells in the corners of the Grid to Terminal. Then, randomly select 3 Cells and set their Value to Terminal.
