This is apparently quite old, but it's news to me.

Are there any frenchies around?

Edit:

This mode is coop stupid and malicious counters waves of zombie increasingly large, you have for example 20 Zombies (easy) has to butt with the 1st round with a Machine-gun, firearm and knife. And gradually that you to kill out of the zombies to gain you money which you will be able expenditure in distributor of weapons that you will find in the maps (generally 2 by map). Quite sour more you will have money plus you will have weapons more powerful, but the zombies are increasingly many and powerful

A mod where you "butt" the first round. Sounds interesting.
