UPDATE: We are moving our assets to Unreal Engine 4, so note that we are no longer requiring you to have Unreal Script Knowledge, everything is coded with C++ so if you have experience with C++ writing codes then please don't hesitate to contact us...
Update: Hey guys! We had a quite interesting amount of applicants who wanted to join for the 3D Character Artist Position which is now closed and taken. I'm sorry for those who didn't get through, but that shouldn't discourage you to continue. Yet, there is an open position - Unreal Script Programmer for the UDK.
