Like others have said, coming from DayZ it really does feel tremendously "simple".
They seem to be implementing a lot of stuff which they took out for Alpha testing soon though.
As you may know we're preparing game update next week, so I want to give you quick glimpse on what to expect.
New map areas
We're going to unlock around 30-40% more of the map space, adding new places to explore - including largest city on the map, jumbo cargo plane crash site and other interesting areas. More spawn points for players, more loot spawns as well. Those who felt a little bit claustrophobic on the map will find this update to be like a fresh air - lots of open spaces, grass fields, etc.
New zombie characters
Yes, we're getting more zombies, and we also add new zombie types - I think 4-5 of them, including "special zombies" - so mutated zombie hunt season will be officially open
New player characters
We have 4 more characters for you. Two guys, two girls. Each have around 4 different skins
Clans
Clans will be unlocked few days after October 31st. You'll be able to create clan, join clan, contribute to Clan Bank or reward your Clan Members from it. You also will be able to see if there're any clan members around you in the world, as well as have their names highlighted on the Players list screen.
More items
More items, especially "building blocks" like barricades, brick walls, etc. Couple cool silenced "improvised" weapons.
There'll be also tons of bug fixes, some performance optimizations, etc...
