DayZ's going stand alone meaning that you'll be able to buy the game without having to pick up something like ArmA III, but it's been kept under wraps for the most part. Until now.
Dean Hall, lead of DayZ, has posted a video of some of the things they have been working on. For the first video, they go through some of the basics such as the clothing and how you can put on layers of different items. Spawn points for items has changed up a bit where things can now spawn in various areas inside a building such as behind furniture making it more prudent to search every nook and cranny of a house.
No zombies are in the video as it's a basic walk through of some of the new engine features and the new swamp areas, but those wanting to see how DayZ is progressing should give it a look,
