Grid Wave

Grid Wave is anti-system program. Originally developed from research done by Langley Microsystems (a sub-developer on the original I-G Net Algorithms) as a company-only tool to test netspace integrity, this routine was stolen and "improved" by "vandal" Netrunners. Simply put, this program attacks the subroutines that make up the I-G Algorithms themselves! By sending out continual waves of netspace distortion that alter the navigation and positional signals of cyberdecks and datafortresses alike, it attempts to "burn out" all objects in a cyberspace area. A Grid Wave attack starts from a single square and advances to 10 square radius limit.

Note: occupants and objects in the center square are not initially affected (runner must make a Very Difficult REF roll in order to jackout immediately after launching the program to avoid its effects). If an object in cyberspace (programs, datawalls, codegates, etc.) fails a 50% roll, it is de-rezzed from netspace. A affected netrunner must make a Very Difficult Interface roll to remain jacked-in. Even if he is successful in avoiding being ejected from the net, his icon is shifted to the edge of the area of effect His netspace movement is reduced to 1 for 1D10 net rounds and his Interface ability suffers a 1D6 penalty 1D6 net rounds. The 1 a square radius area cannot be entered for 1D6+4 net rounds (it doesn't exist!) until the local netspace servers rebuild the area.

Warning: use of this program will be immediately picked up by Net Watch within an area up to the size of a city subgrid.
