As you know when you are Half-Life fan, There are 2 feature main games, 2 expansion packs for Half-Life 1, Two episodic games for Half-Life 2, a spin-off series called Portal and a upcoming VR game called Half-Life: Alyx coming next year but there is one Half-Life game that was planned to come out in Christmas 2007 that was never released and it's now vaporware, and is called Half-Life 2: Episode Three, here's the story:

While at high school, my best friend of mine said that his father works at Valve and his father said a copy of Half-Life 2: Episode Three exist somewhere in the Valve Coporation headquaters, this get me excited because i think my dad, who also works at Valve would find it, while my dad was leaving the Valve headquaters, he stepped on a DVD disc that says "Half-Life 2: Episode Three Beta Version 2007, PC/Mac only, Confidential", he grabbed it, went home and show it to me, I got very excited and i grabbed the disc from my father's hands, i ran to my room, installed it on my Dell OptiPlex GX280 with Nvidia GeForce 210 graphics card and played the game, It showed the Valve logo and went to the main menu as normal, i started a new game and the games begins, it began Alyx Vance crying for his father's dead body until the G-Man showed, he brainwashed Gordon Freeman, and Gordon Freeman started a murderous rampage, i proceed to kill Alyx, and all the Resistance fighters and then surrender to the Combine and then all humans are dead, After that, the game cuts to Gordon Freeman, Alyx Vance, and all the Resistance fighters in Hell, turned into ghosts by the Devil and then the game ends, What the fuck? Then i got freaked out and i got nightmares about this game, Here's the aftermath:

2 Days after i got scared by this game, i decided to make a playthrough of this game and uploaded to YouTube and i made the ISO of the DVD that my dad gave it to me and i uploaded on MediaFire.
