If the invasion occurs in a highly populated district, though, you can expect it will be short (typically less than 10 minutes), since there are plenty of toons fighting cogs. The actual number can vary based on conditions which are not important, but the upshot of this is that it is difficult to predict the length of an invasion. Invasions last until a particular number of cogs are eliminated in the district. They remain the type particular to the venue.) (The exception to this is that the cogs in the HQ and Boss runs, such as the factory or the CFO battle or the mints, do not change.

If you are in a building and an invasion ends, the cogs will revert when you reach the next floor.

When it ends, the cogs in the streets all fly away and the district reverts to the standard mixture of cogs. Hollywood invasion, for example, every cog in the street and in a building will be Mr. All the cogs currently on the street fly away, and are replaced by the type of cog which is invading. Invasions are times where all the cogs in a district (in all the streets and in all the buildings) change to one specific type of cog. If you would prefer to get the same result in half the time, read on. This can mean hundreds or even thousands of hours saved in the process of maxing your toon. Understanding how invasions work is an important tool in the game, because points awarded for using gags (and for completing HQ runs) are doubled if an invasion is going on.
