would be nice if there was a whole system of sewers connecting towns cities, giving new dynamics to entering towns, fleeing and flanking. fantastic cover for the light of day and adding a surprise element and anti sniper control. bunkers and labs that have epic loot but are only accessible by the right access card clearance found on military and scientist zombies. i think that an experience system in the game would be good, yes it might seem a little unrealistic but would give add a bit of a goal in the game to develope a path of a characters traits and abilities. such as military abilities like more efficient with firearms. medical like doctoring skills. crafting when base building is in like sturdier bases and stuffs.
