Wasteland, the original post-apocalyptic RPG game will have a sequel as Wasteland 2. Brian Fargo who Executive Produced both Wasteland and Fallout will be heading the team.
Wasteland 2 was on Kickstarter for last few days with a target of $900k. A Linux version was promised at $1.5 million funding and they have made it to this mark.
So yes, there will be a Linux version and you can confirm a DRM free copy for yourself for $15. The game won't be a first person shooter. With a top down perspective you will get a tactical feel for the situation. It will be turn based, tactical, with a storyline that will be deeper and broader.
From kiskstarter page:
Wasteland 2 is the direct sequel to the first ever post-apocalyptic computer RPG. The original Wasteland was the inspiration for the FALLOUT series of games, and the first RPG to allow players to split parties for tactical considerations, to face players with moral choices, and to make them deal with the consequences of their actions. It was the first to provide far more than the one-key-for-one-lock style of puzzle solving.
Wasteland was set in a dangerous, post-apocalyptic world in the American Southwest. Over the course of adventures rangers would receive promotions, acquire new skills and equipment, then face new challenges with outcomes that changed depending on the strategy used to defeat them. The game featured a strong storyline which required painful decisions by players; and a storyline that allowed for maximum re-playability. Wasteland 2, with your participation and insights, will recapture all that and provide more. It'll finally be the game worthy to be a Wasteland sequel, as challenging and rewarding as the original, with all added capacity and dazzle of games today.
25 days are still left in the campaign. Grab your copy now as after the funding is over prices could be raised.
