Okay, so basically what if an extra zombies mode were added that was objective based, left 4 dead styled.
Tbh when I think about it, id rather say a more "no room in hell" style, you have to search rooms or locations in the level for weaponry, along with limited ammo and resources, and using your melee weapons or fist is more recommended, that way in combat, you're conserving ammo a lot more and holding on till you reach greater amounts of enemies that require more firepower to push through. On top of that having different objectives, say one is some random objective from a military standpoint, and others are like survivors just tryna escape with their lives.
I haven't seen anyone talk about this when I search up zombies at all here, so if someone finds a post very similar to this I'll take it down and add to their idea that way they get credit. 👍
