Alright this could be a pretty cool event where there would be a city wide power outage due to a few pesky birds (Yea fucking annoying birds from portal 2.) So the overview of it is that a flock of birds are on migration and decided to take a stop for food in City 45. But at the realization of the city is full of stingy assholes citizens who can't spare food they are to tired to keep moving on. In an attempt for food they start pecking at the power wires around the plaza and nexus. Most of these birds weren't effective 'till a little bird name "pideon" takes one peck at a nexus power line. This causes a city wide black out. The thumpers stop working due to the outage and then the Antlions get in. All lights and Combine locks and doors shutdown in an un-openable state.
