Well what Silverlan has done is implement a new system.
This system allows the custimation and creation of the players. There are many different and verious stuff that allows little resemblence between two characters, such as colors, races, and types of hair and faces that allows player to make them feel like their the master of their characters looks.(Aswell as character's persanality :P) As I also abserved that many havent seen and watched at the new gameplay video that Silverlan has made, it aswell shows new systems that have been crafted into the gamemode. This system is the weather system, the spell system, pet system, and the menu system.
You may view these things in the media here in moddb.com and at the the main page.
Also do not forget to view and join the gamemode main page which can be found here on this link Gmodaftermath.com.
Thank you for reading this and having to bear with me.
