Pretty much title. I’ve noticed that whenever groups of players are forced to move around to different parts of the map, it ends up with a much more challenging but rewarding gameplay experience, usually because they have to move out of their predetermined camping spots and move through different zombie spawns.
For example, in Village, there is not much reason to leave the little fountain/road part you spawn in besides moving to the helicopter. Tons of cool different paths and spots end up going unused.
Whether it be through encouragement, (supplies, extra points, more weapons etc.) or through force (eg. more zombies spawn if you stand in a place for long enough), I would definitely like to see this happen somehow. (If anyone has any deeper suggestions I would absolutely love to hear them)
