Nightmare House 2 is a free, horror-themed first-person-shooter game, and the direct successor of the first classic horror map pack for Half-Life 2, "Nightmare House" in 2005. Nightmare House 2 is based on the Source Engine by Valve. The mod is to continue the bizarre story of the stranger who had the misfortune to crash his car outside an old house with a horrific past.

A free flash game inspired by Valve's Portal. This fan created game shares the same mechanics, objects and themes as the original Portal, however it's in 2D and has a male protagonist. Portal: The Flash Version started as a Flash project by Hen Mazolski and Ido Tal, back when Valve first announced about Portal. This may be the reason why this flash game and the objects in it (such as the crusher) resemble the ones in the trailer more than those from the released game.

Nightmare House is a single player HL2 map pack and the first episode in the series, created by Hen Mazolski in September 2005. This edition of Nightmare House has considerably less custom content than its sequel. It has since been supplanted by Nightmare House: Remake, and integrated into Nightmare House 2 as a prologue.

No sleeping beyond this point. Slash through nightmares, twist reality, and uncover the hidden secrets of Nightmare House.

Portal: The Flash Version MapPack is a remake of the namesake Flash fan game for Portal. Some of its chambers were included in Portal: Still Alive.
