landscape

when you are bored and have high mountain near you..

like terraform ;?) just take shovel and go dig!

another landscape (from top of this mountain where I was climbing second screen shot)

fighting system is also uniqe.. it's pretty similar to mount and blade system

want some raids? :) they are pretty often on wild server ;)

sometimes I don't believe that it's only a game...
