Updating their recently launched Kickstarter pledge-drive, developer Cliffhanger Productions has responded to community-feedback and added a new pay to own option for the game that they are likening to NCSoft's Guild Wars model.

The project was initially announced as a free-to-play title with micro-transactions, with an optional ongoing subscription model with a host of benefits. However, the newly announced Campaign Model sounds like it will fit in somewhere in between, offering an initial purchase with a finite amount of content.

Listening to what Shadowrun fans and gamers want, Shadowrun Online will now be available as a dedicated client for PC, Mac, iPad2 and up, as well as Android Tablets. This level of community engagement also resulted in the decision to add an additional, completely new way to play the game: The Campaign Model. It is a Pay-to-Own revenue model, similar to Guild Wars or classic pen and paper games.

You buy the game once for the going price of your typical game, or for just 25$ for Kickstarter backers. Then, you can play it forever, just like any single-player RPG. And, unlike most MMO's, which charge a monthly subscription fee, or sell in-game items, you can instead decide to later acquire expansions such as new campaigns or additional cities.

A new trailer offers the first footage of the game, described as early prototype gameplay, and you can watch that below (or here in HD.

With 19 days remaining, Shadowrun Online has currently raised just over US$137,000 of its US$500,000 goal. If you'd like to get in on the action, head over to the Kickstarter page.
