The recently announced standalone remake of the popular Arma 2 mod DayZ could be coming to us as early as this year. The planned title (according to Deal Hall) is going to be set in a revamped Chernarus, in addition to new maps, with more buildings that can be entered than in the Arma 2 mod (which is fantastic).
There will also be instanced areas, which may or may not be a plus for some players. Players will be able to dig underground bases and build them to their liking. The bases can be entered via a portal, in this case, an iron grate in the ground. Inside of these instanced spaces, you probably can’t get attacked by zombies, so there wouldn’t really be as much suspense involved. It is an interesting idea, however, and perhaps a sense of safety is something that is much needed for players in this game, at least sometimes.
