What about making a map where there would be one team of 10 players fighting bot zombies? Maybe an simple AI would suffice. For instance, zombies would start blocking when Gunner´s canon is in their way and firing on them. Of course they won´t block traps and magic. There could be also other zombie classes like runner,tank,etc...

Just think of all the posibilities... Players would defend points like in Orc Burghwall. It would be not time limited map and zombies would continualy spawn over time. To every point captured by the zombies there would be added graweyard from which spawns additional zombies + zombies from they first spawn graveyard. However, as soon as zombies claim one certain spawn point, it can not be reclaimed by players. This way the match shouldn´t last forever.

Let´s say that zombies at lvl 1 players map would have 700 or 800 HP so a gunner may crit him with hammer one shot. When runner´s get hit he can sprint forward and drain from his energy. Tank could have like 1500 or 2000 HP and he can do some area of effect damage ability.

This way we will make players work together like never before. Of course, the map will be rolled randomly like all other maps so there will be enough players for all the maps.

Now we don't want this game turning into cod now do we?

I kind of like the idea. Seems very fun, but it needs to be improved before adding it officially.

this game needs pvp and pve, this would be a great pve map if the maps were bigger, so you can base in different spots, and make it where each class has a pve tech tree allowing the gunner or w.e to build the cannon and Walls, so you can build walls to keep zombies allowing you to build fortifications and making it where to build stuff you have to pick up material off the ground around the map so you cant just camp in your base you have to run out and search, or have other classes go out and search for you.
