We are working towards submitting the game to Steam Greenlight.
This should happen within the next 2-3 weeks.
The submission to Greenlight will coincide with the release of version 1.2 of the game, along with a fresh game demo.
The demo will contain more content from the full game and feature some improvements over the previous demo, e.g. we plan to add a shooting range map where you can try out all of the weapons available in the game.
We will also release a long play video of the full game that will show why the gameplay is so addictive :-)
