Ok so just so everyone understands.

There is about 5 grenade sized canisters on the main floor.
Once settled they released a chemical compound that quickly reacted and glued/cemented them to what ever surface they were on.

They are close to running out of tear gas now but it still hangs heavily in the room with very little airflow to make it do otherwise.
Each one is strobing like a flash bang grenade and functioning like one of those house alarms designed to make an intruder pass out.

We should work on dulling/stopping them. 

Also. 

Viscious attack dogs circle the perimeter and small drones have started coming into the building. 

You can assume they are equipped with anything you like as each may be individually purposed.
