The developers of Steel Storm sent in the following announcement:
Finally, we are out of beta stage and proudly announce release of Steel Storm Episode I v1.0
The release includes a lot of visual and functional improvements. A lot of work has been done under the hood. AI is more advanced now and have no mercy indeed ;)
According to the majority, the game was too easy, especially in coop. Now the game is more challenging and more coop oriented. Get ready, exercise your spinal cord ;)
Another major feature that comes with the release is SandStorm, real-time mission editor. Basically you can start building new missions and modify existing ones.
As soon as we release training videos, we will hold contests and tournaments for Steel Storm Episode I.
Full list of changes and additions can be found in the changelog.
You have to uninstall older version of the game, download full release and install it on your PC / Mac.
The official servers have been updated and they require client v1.0.
We appreciate you patience and your support. Enjoy the game!
