Ok almost there...
Before Allison could reach the Rendevous point she received another message "Allison, Katya i want you back here imediatly. we are CODE RED, Repeat CODE RED". 
[i]They are attacking HQ? Damn, was it all just a bait?[/i]
Instead of moving to the point Allison turned around and was heading to the HQ now. Meanwhile she contacted Katya "You received it too huh? Little change, the new Rendevous point is at HQ, contact the other teams as well. Since I am closest to HQ I will head there immediately, Allison out.".

Soon she arrived at the main entrance gate to the base, usually there would be a guard out there, but no one was at sight and the gate was open. 
Allison loaded her sub-machinegun with a new magazine, then she entered the base.
[i]I hope I am not too late to the party![/i]
