Your question has been posted in the wrong place.
However the question you have asked would suggest you wouldn't know this, it would also suggest that you are using the web based game and wouldn't know how this works against computer players.
Yes there will be more invaders and ghosts , but they will show up much later and in order to see them,you may have to reload the game as well.
