About This Game

1998. HALF-LIFE sends a shock through the game industry with its combination of pounding action and continuous, immersive storytelling. Valve's debut title wins more than 50 game-of-the-year awards on its way to being named "Best PC Game Ever" by PC Gamer, and launches a franchise with more than eight million retail units sold worldwide.

NOW. By taking the suspense, challenge and visceral charge of the original, 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, from the physical environment to the behaviors even the emotions of both friends and enemies.

The player again picks up the crowbar of research scientist Gordon Freeman, who finds himself on an alien-infested Earth being picked to the bone, its resources depleted, its populace dwindling. Freeman is thrust into the unenviable role of rescuing the world from the wrong he unleashed back at Black Mesa. And a lot of people he cares about are counting on him.

The intense, real-time gameplay of Half-Life 2 is made possible only by Source®, Valve's new proprietary engine technology. Source provides major enhancements in:

  • Characters: Advanced facial animation system delivers the most sophisticated in-game characters ever seen. With 40 distinct facial "muscles," human characters convey the full array of human emotion, and respond to the player with fluidity and intelligence.
  • Physics: From pebbles to water to 2-ton trucks respond as expected, as they obey the laws of mass, friction, gravity, and buoyancy.
  • Graphics: Source's shader-based renderer, like the one used at Pixar to create movies such as Toy Story® and Monster's, Inc.®, creates the most beautiful and realistic environments ever seen in a video game.
  • AI: Neither friends nor enemies charge blindly into the fray. They can assess threats, navigate tricky terrain, and fashion weapons from whatever is at hand.

A legendary game, Half-Life was. An even more legendary sequel Half-Life 2 was. But even now, it's excellent, if a tad dated. (But not even that much) Solid controls, fluid gameplay, and enough challenge and fun for both newcomers to first-person shooters, but also hardened veterans of the genre! A sequel that not only lives up to the original, but surpasses it! Not to mention the fact the story is excellent, and has complex characters who all seem so real I felt like I could reach out and touch them. Also, don't worry about whether or not your computer can run it, as it rarely crashes, and runs on most PCs quite well. (Take it from me, my PC can't even run CS:GO properly!) It pushed the boundaries of gaming back then, and is still quite a sight to behold, so whether you're in it for the action or the story, pick up the game and prepare to enter the distopia of City 17!

I have over 9 house on HL2 so i guess you can say i have my spent plenty of time on the game.So after playing this game for so long I have came to a conclusion, that half life 2 is one of the worst game made by valve.
for 1 The main character doesn't even speak.Could they not afford the voice actor? something else the story line is sooo boring i mean i didn't even finish it like god. If you want a good story line play play Cod.

Half-Life 2. The video game that started the modern generation on first-person shooters and revamped the gaming history into a new era. Originally released in November 2004, the game won multiple game of the year awards and branched gameplay mechanics, including physics and the state-of-the-art game engine that look realistic during its release date. Many people are aware on the game’s popularity and everlasting legacy including various jokes on the awaiting sequel (for many years), but the question remains: Why is this game popular?

The game takes place after the events from Half-Life. You play as Gordon Freeman, the silent protagonist who got a Ph.D. on theoretical physics at the Massachusetts Institute of Technology (MIT) and knows how to use weapons very effectively; a strange paradox for a character with such features yet highly popular and well-recognized. You are sent to City 17 by the G-Man, a mysterious person or a phenomenon with a mysterious and ambiguous agenda, to overthrow Wallace Breen and the alien oppressors, the Combine. The setting and lore in the Half-Life universe is simply the best, taking some influence from George Orwell’s 1984 or other famous dystopian novels to set the story in tone. Gordon’s influence and previous actions will spark oppressed citizens in City 17 to take arms and revolt against the Combine. From City 17 to the prison at Nova Prospekt, each setting is unique, bleak, but beautifully designed, the game simply defined what a video game should be.

Each NPCs and major characters such as Doctor Issac Kleiner, Barney Calhoun, and other characters interact realistically among each other and to you. In regards to Alyx Vance, your ally and companion, Valve spawned the concept of AI teammates and became a true asset in your journey to rally up the oppressed citizens. Besides good character developments, the best attribute for Half-Life 2 was physic interactions and the game engine. The game engine is Source, which feature high-dynamic range rendering, facial animations, and “realistic physics”; the first game that had such a feature like this.

Are there criticisms for the game? I believe so, but to be honest, I couldn’t find any legitimate criticisms for the game. If one criticism has to be addressed, then the problem is the loading sections. Yes, those tedious loading that interrupted the “flow” in the middle of a long level or after finishing a series of firefights against Civil Protection or Combine forces. These loading or “checkpoints” really halt the immersion in the game. However, this is very common on all Half-Life games and I hope that Valve would address this (if they are working on the sequel…).

Half-Life 2 is pure gold, shining flawlessly on the test of time. With great graphical fidelity at its time, voice acting and realistic AI interaction from your allies and enemies, this game is a rare exception of genuine perfection and grand role model for other game developers to pursue their own game designs. The only thing Half-Life 2 (and its episodes) is a full fledge sequel. Besides many jokes, anxieties, and waning patience for Valve to announce the sequel, the game should be in every PC gamer’s Steam library. No exception. Half-Life 2 is simply the best; a grand overture that started and defined the modern gaming industry in the present time.

This is one of the best games ever made, you got puzzles mixed in with shooting and one of the coolest weapons/tools in video game history, the Gravity Gun. Let's not forget the story, it's great. The graphics are probably one of the biggest highlights, especially since the game is from 2004. Hard to believe this game is that old!
