4 arenas. 15 waves per arena. Each wave has an optional challenge.
I can see why for people who want to beat the challenge this can be frustrating. That's because if you fail a challenge then the only way to try it again is by going through all the previous waves. You cannot jump directly to a specific wave.

If you are not driven by high scores and completing the optional challenges then this is really good fun. Some levels are ridiculously difficult. If you die you can just carry on from where you are in a wave, you just automatically fail the challenge.

If nothing else, use this DLC as a training ground. Playing this I discovered how good the handgun is !! I also discovered the charged melee seems good against the handyman - however, yet to try this out in the main game.
