Gamers can elect to have their game released on Steam as well.
According to the developer, "Steam access is a convenience for some people who prefer to keep all their game keys in one place. If you wish to move your key to Steam, you’ll be able to once the game is live on Steam. If you wish to continue to simply play though our own service UberNet, you’ll be able to. No action is needed at this time for Steam access. We’ll send information once Steam keys are available for use. It also means it’s our first digital distribution platform besides our own, which means another way for the community to grow further and bring in more players.”
The developer released a video describing how alpha testing would work.
