Here's a map that someone made and posted on Reddit: https://www.reddit.com/r/CODZombies...ours_later_ive_finally_finished_my_black_ops/ Now that's not a server but it's a great platform for thinking about a fun multiplayer gamemode. If you've played the MobArena plugin you know what I'm talking about. Combine the two concepts. Waves of mobs and some bosses. Advance through the map by defeating enemies. Bring a good crew along or you won't make it past the later stages. They can't be solo'd. Revenue could come from loadout kits, so basically call it KitPvE.
i personally think this is a good idea. however, there should be a change in style. maybe focus less on the zombies. also u have to keep in mind the amount a server can handle. what version do we use/is recommended.
