Hey guys, the Adminpwn has updated some new missions every day. He said thaty he'll make a addition of 60 mission in total!!! Check the dead frontier wiki for every new mission update. http://deadfrontier.wikia.com/wiki/Missions

This is what the Adminpwn said from the development blog:

“I'm just writing to let you all know that I'm still alive, and that Dead Frontier will be a getting another large update in the next month or so. Here is what I'm working on right now: ■New Missions. I'm looking to add total of around 60 new missions to the game. In addition, there will be two new missions per day rather than just the one that happens currently. I apologise that these have been such a long time coming.
■Larger Inner City with a new, much harder end zone.
■Increased level cap. The new maximum level will be 220, allowing players to completely max out their stat points.
■A massive range of new standard (non limited edition) equipment. Everything from weapons & armour to purely cosmetic items. We're looking at close to 100 new pieces in total.
■Various improvements & updates to the weekly Top PvP and Top Survivor competitions.
■Dead Frontier: Outbreak 3 :D
■A bunch of general bug fixes and optimizations to the game client.“
