Sim Hero will "officially" release on December 1st.
What does that mean? Well, it's free to play now... will be free to play afterwards. Might always be free to play, we'll see if maybe a Steam Greenlight campaign is in our distant future (we'd want to have all our own art assets in place before we try that though).
One more major update is on the way, which will include:
- more lag fixes
- more UI improvements
- more content
- various bugfixes
Stay tuned!
