Description from its website:
Duplex Systems is a development studio fully dedicated to online entertainment software.
The company was founded in 2001 with the birth of our first massively mutliplayer online (MMO) game title. The studio now has more than 7 years of MMO experience from planning, developing to releasing and hosting such games.
We explore the fascinating levels between the real world and virtual realms.
However, it is not our goal to find a replacement for reality, but to extend it. We never fear the risk of trying to implement the most unique new gameplay elements. It is our philosophy, that, in the end, these voyages turn out to be the ones that leap us forward.
