Editing Challenges

There are currently 10 challenges in the game, each of which modify how the game looks or plays.

Every challenge starts the player with 100 health and the [[Weapons|Pistol]] with no secondary or ultimate abilities. Except in the Mega Boss Rush Challenge where the player won't have health (Like [[Odr]]).
