I am myself searching for revival seringues right now and I found one so far. I do have the skills to use them, so it's all for the best.
For the HQ; there is nothing of interest there so it's better that you guys stay either in the NT building or the PD for now anyways. Those of us who have free running can get there.
Edit: someone in the NT building bashed down on someone who was baricading the building too much. He said to head 1N and barricade that building instead, so we have to expect people in our HQ in the near future.
