Early access, but one of the treasures. Zombie crafting game with surprising depth. Constantly being improved. Great 1P, I hear it's good multi too.

Everything good about Dead Space, plus a continuation of the plot and even more harrowing encounters with the space-undead.

Very good atmosphere, along with novel weapons that aren't just your usual pistol/shotgun/machinegun/rocket mix. Highly recommended.

Orcs break through. Orcs try to get to the rift. Orcs get sliced, diced, spindled, minced, mangled, and splattered by traps. Good times, good times.

Vaguely inspired by an obscure Russian movie, this game has a rather unique atmosphere. Hybrid FPS and RPG, and good for many hours of solo game play.

Rogue-like magic-based FPS in the vein of Heretic/Hexen from the days of yore. Good for a quick blast through to kill some time.

Space battles on a huge scale with relatively well-balanced factions (some of which are sadly near-clones) in a fully rotatable 3d universe.

Western first-person shoot-em-up. Kill everything that moves. Main character is a delightfully cynical old codger.

This is like a Charles Dickens story if he were doped full of antidepressants. Everyone is a cheerful orphan doing dangerous work to keep eating.

A combination of stealth, combat, and magical powers. It's rather impressive when a game can make stealth work when combined with magic powers.
