The monsters can move in a serpentine or straight forward fashion.
In addition, you can select from multiple difficulties which decides how fast the monsters move and how strong they are.
Although there is only 3 difficulties, you can mix them together to create harder challenges (a total of 7 difficulties if you look at it this way... example: you can spawn the Easy and Medium waves spawning at the same time).
Be warned though... activating all 3 difficulties at once will be very difficult.
