When you start the game you can pick a difficulty level, which can be easy, normal, or hard. [list] [*] [b]Hard[/b] is the original difficulty with several additional threats added. [*] [b]Normal[/b] has additional support platforms. [*] [b]Easy[/b] has additional respawn points, which look like green checkpoints. Just to let you know, they are not checkpoints, to save your progress you need to reach a blue checkpoint. [/list]
