GMDX has also gained a new team member! He's a talented artist that goes by the alias '"Barbeerian", and intends to aid GMDX fulfill its potential by adding a variety of new art: 2D textures, skins, models and animations.
Here's a shot of the very first asset contributed in its early creation stage, a helmet model:

I'm always looking for new team members to push Deus Ex at an accelerated rate and cover other fields of design, so if you're interested send a PM.

Are there SDK's available for this engine? Specifically the Deus Ex version?

Reply Good karma Bad karma+3 votes

Nope. If there was an SDK for DX:HR, it could be modded by the community and made into a good game - but you can thank Square Enix and Eidos for that.
