The ground assault team had completed the first phase of their assault with the construction of a compact NNEMP device. Four small fusion reactors powering a non-Nuclear Electro-Magnetic Pulse weapon. They all called in the completion of their own devices, and Rodero started the synchronous timer for two seconds.
In the lift shaft Drick and Marsh both stopped their descent and locked themselves to the cables. They turned on the dampening sine-wave emitter that was keyed to be in perfect harmony with the pulse of electromagnetic energy about to be unleashed. The device was designed to work in perfect time with the EMP, same frequency but out of phase to lessen the effects.
Rodero set a system to enter into a critical loop. It was the absorption battery relay. A minor system in the buildings anti-conflict defences. The relay itself merely allowed electrical charges to be distributed towards batteries, the main grid, or to a ground spike. The critical loop forced the system to temporarily offline while the loop was broken. At that moment the entire of the anti electronic assault defenses were offline and the systems as exposed as they could be to the effects of electro-magnetic spectrum attacks.
The counter in the views of the assault team reached zero. The whole team suspended all electronic equipment and braced. A microsecond before the powerful pulse was emitted.
Anyone looking at the building would have seen very little in regards to this initial dramatic assault.. A few sparks as electrical discharges flicked across materials of competing charge. Some minor explosions from circuits that flash fired into a sudden death. The most noticeable display was the sudden loss of light from any source. LEDs blinked out, camera lights turned off. Systems shutdown or turned to safety modes which resulted in every door, except a lift or security door, opening to allow easy movement.
A moment later Drick flicked all the systems on the monitors to full assault mode. At the same time the clones flicked theirs to active assault. Marsh and Boomer followed scant moments afterwards. The signal to Rodero by the upstairs link came back online a second after that. The assault had begun in earnest.
