Neutron Purge Device for labs. Basically a small neutron bomb or a system with a similar effect integrated with the facility. When activated will completely purge the facility of both organic and mechanical enemies but leave the lab intact (will kill the player too if you don’t get out in time). High computer skills required to activate properly, and should be somewhat difficult to get to as well, but it might be a better option than clearing the entire facility manually depending on the size and what is presently infesting it (@Maverick’s escaped shoggoth horde is an excellent example of a neutron purge worthy situation). Besides, who on earth would build a lab for researching horrifying/dangerous shit without adding a self destruct or “kill everything inside” button.
More useful data downloads from computers in military bases and labs. Recipes, blueprints, and last known locations of military forces and science teams (potential salvage sites for weapons, armor, military vehicles, technology, etc).
Remote control drones, both off the shelf variety and things like military/police bomb disposal robots. It would be nice to scout out cities, bunkers, etc remotely with something relatively disposable. Would be good as a distraction too.
