We are now in final stage of preparing version 1.0 of our new game. For 3D it uses Irrlicht, with a lot of modifications.... to mention a few:
3d textures, tessellation shaders, pointers to user data in materials, optimized occlusion queries, hardware particles, custom vertex formats and render target blitting.
We plan to 'give back', some of these functions, to Irrlicht
The game also has multiplayer servers in the cloud, so all users instantly have access to online gameplay, in addition to LAN servers.
We will add screenies here in a week, stay tuned !
