This is really really little compared to how much it takes to trek/run from south to north on Chernarus map (never did the full distance myself but I believe it's about 3-4 hours of running).
No, no, no, nothing like that. To Stary Sobor it's about 25 minutes from the coast. Doing that twice brings you at the height of krasnostav, from there on out there is little to the map then trees. Probably about an hour and 15 minutes to the complete edge and an hour to the last point of interest. You run about 18 km/h though, which is something to keep in mind when comparing, might be a bit slower in WarZ, cause that is pretty fast.
But that standalone will be using horriblé Arma engine won't it? I'll pass.
Well, being able to support a 225 km without loading times, with 600 zombies, 50 players, loot spawns, zombie spawns, day/night cycle, excellent light effects, weather, physics and yet looking quite beautiful at times, I would not call that a horrible engine. Actually because it was based on Arma was the reason it was so interesting, it had this realistic feel to it and the enormous size of the map made it even more awesome.
It has its quirks, but I'm eager to see what they can do with an updated version of it that is actually aimed at making a zombie game.
