Yes, we finally made it through!
Our 3D FPS game Chicks Attack is out - and you can find it here :

The game was made with Unity3D engine and the multiplayer functionality relies on Appwarp network game engine. Had a bit of pain in terms of callbakcs management and different players' sync, but in the end the result seems to be satisfactory. Hope you agree? Give it a try! It's a free game with ads only.
Cheers!
