FOXALIVE

FOXALIVE is a computer virus, and the conceptual opposite to the FOXDIE Virus. It was designed by Naomi Hunter and Sunny and was to be inserted into GW, one of The Patriots AIs housed in Outer Haven, where it would destroy it and render Liquid Ocelots mighty army useless.

Unknown to Solid Snake (who risked his life to enter GWs chamber) and Otacon the virus actually used GW as a gateway to destroy all five of the Patriots AIs, and rid the world of them for good.
