Challenge Mode

Challenge Mode is a game mode in Call of Duty: Heroes. The mode has the player pick five types of units and three heroes to attack as many bases as possible. Each unit has a limited number, which when used isn't retrained. If a hero dies, they cannot be brought back unless the player chooses to redo a level for 100 celerium. The player is also given 950 skill points for their heroes.
There are seven areas the player is able to attack, with each one requiring the previous to be beaten before the next can be played. Each level gets progressively more difficult, and as a result has better rewards. The maps are different each day, as are the possible units.
The player is able to restart once every twenty-four hours, allowing the player to select new troops and heroes, but having to start over again. This is one of the only ways Challenge Coins can be acquired.
