As of right now I havent decided if DLC will be free or not, but chances are it might be and I will do what GTAV did and release them with updates.

But there is the weapons list

As for updates, I am working on the weapons engine right now, ill post a demo later on. Theprevious weapon demo we have is primitive, but it will be posted sometime this week, so you all have a feel for what the game will be like.

Expected Demo Launch: March 2015
