The Dead Linger is an FPS that embodies the gaming community's hunger for a true, open-world, zombie apocalypse survival sandbox! Set in a planet-sized world, survivors learn to fight, run, and survive against the never-ending and relentless zombie hordes. With pure sandbox, free-roam gameplay, multiplayer, exploration, free-form barricading, physics, and intense realism, this is the zombie apocalypse experience you've longed for all these years. The zombie genre has died. We're bringing it back from the dead.

The idea behind this game is awesome, and Sandswept's dedication to it is refreshing.
Sandswept is also very open about development.
Sandswept is a great team, and I trust them to realize their vision.

As for the game itself. It is very rough around the edges at the moment of May 8th 2013. In early alpha, but already it has some very interesting and unique features, including several I've never seen before in gaming.
Features currently include...
All doors can be opened using a unique system.
You can be infected with the zombie virus and turn when you die.
Zombies can only die from headshots.
Coming soon, Freeform barricading. Grab a piece of lumber and a hammer and nail it to anything, including more lumber.
