While a majority of the content for Alliance Unbound is for high-level characters, there's still plenty for lowbies to do as well. The main update quest line opens up at level 15 and offers both a high- and low-level version.
The update has plenty of meat to it in other ways. A gigantic 31-part quest chain has been added to Ellin Forest for level 95s in which players will jump back in time and explore the making of one of the key regions in the game. There's also a nifty and powerful alien socket system that grants players the ability to upgrade weapons. Finally, Nexon's got plenty of new Event Cards and a collection system to keep players busy.
