The developers of Reflex have pulled the plug on their Kickstarter campaign, as it's unrealistic that the goal still can be achieved (10 days left, 81k/360k pledged). The project won't be abandoned though, as it has been greenlit on Steam and is being prepared for Early Access. If Linux support is still on their list is questionable.

Reflex is a competitive Arena FPS that combines modern tech with the speed, precision and freedom of a 90s shooter. It may become for Quake what UT is for the Unreal series. The game just went on kickstarter and Linux is on their list!
