Warning code x24: Intruder may have self-modified

You play as a hacker, launching a new self-modifying virus on the corporate network. Control the virus through different servers. Destroy the anti-malware programs that come after you and absorb their code to create new attack vectors.

Controls:
Mouse - scan surroundings and target applications
WASD - move virus
Left mouse button - fire
Right mouse, Q, E - change application schema, configured at hyperlink terminals
Escape - set breakpoint
Partial controller support (360 compatible)

Changing schema allows your code to bypass or more effectively target certain anti-malware executables. Changes will be quickly detected and will reset automatically. The change is represented visually in your terminal.
Visual schema:
Triangle - normal
Circle - provides redundant code as a decoy to absorb possible counter measures
Arrow - high performance, zero detection rate, but runs to completion quickly
Square - imprecise, but wide code coverage
Curve - limited read-ahead, but attacks with many different vectors
Funnel - precision heap corruption

Some anti-virus software is more advanced, and contains large threat dictionaries. Core vulnerabilities of these programs will be highlighted yellow or purple.
