Low Tiberium contamination
Blue Zone (2047)
A Nod stealth taskforce, composed of Shadow Teams, Specters, and Stealth tanks, infiltrated the facility just prior to the outbreak of the Third Tiberium War. The team stole vast amounts of funds from the Treasury, but their main objective was to keep Treasurer Boyle busy, preventing him from attending the Energy Summit on the GDSS Philadelphia. Kane thought that having such an egoistic, short-sighted buffoon leading GDI would greatly aid Nod in their objectives, and therefore decided to save him from a fiery death on board Philadelphia by keeping him on Earth.
The mission was a complete success, dealing billions worth of losses to the GDI and successfully delaying Boyle. Most importantly, the GDI was completely unaware of Nod's involvement in the attack, and believed that it was conducted by the Sons of Umagon, a militant mutant separatist group.
