Pick up the crowbar of research scientist Gordon Freeman, and find yourself on an alien-infested Earth being picked to the bone, its resources depleted, its populace dwindling. You must rescue the world from the wrong you unleashed back at Black Mesa.

The original Half-Life sent a shock through the game industry with its combination of pounding action and continuous, immersive storytelling. Valve's debut title won more than 50 Game of the Year awards, was named "Best Game Ever" by PC Gamer, and launched a franchise which has since sold over 11 million units worldwide. By taking the suspense, challenge and visceral charge of the original Half-Life and adding startling new realism and responsiveness, Half-Life 2 opens the door to a world where the player’s presence affects everything around him or her, from the physical environment to the behaviors and even the emotions of both friends and enemies.

Technical note: most mods “for Half-Life 2” are actually cross-compatible with all of Valve's Source engine games. Check a mod’s profile for details on whether a specific game is needed.

Russia was worse than Germany, and Stalin killed far more. I'm not saying make a game on the holocaust. You do know Germans ARE humans, right?

Highest Rated (20 agree) 10/10

Sadly it never ends for Gordon Freeman, he is gaming worlds Jack Bauer, consistently going from one bad day to the next. No sooner have you blown up the head of the Xenian Nihilanth and discussed career prospects with the mysterious G-Man than he tosses you in the mix again. Another train ride another mysterious situation leaving Gordon (and you the gamer) none the wiser, but thats what we like about the Half-life series and all it's canonical universe, Valve will always give you a Palm d'or plot…
