1. New Techtree:
2. New armor
3. New vehichle
4. New weapons
5. New enemy

I failed to use Unisprite studio - it crashes on start for me on Windows 7x64. Links for How-to looks dead. I completely do npt know where to start at this point. Please, help.

It's impossible to give any specific answers without specifics.

This is your most important resource. Start with something simple, preferably with pre-existing graphics. Ask lots of questions.
