Gordon Freeman, the crowbar packing scientist, returned with a blaze in Half - Life 2. The game is exactly the same as the PC version, so don't expect anything new elements to this one.
This game isn't for those looking for another "run in, blow everything away, rinse, repeat" game, this is another breed of shooter gaming. As i said, Freeman is a scientist (he has an MIT degree, which is noted a few times in - game), which means he's ridiculously smart. There are points where it throws many puzzles/chokepoints at you, which require mental thought and processing. Example: you come across a bridge that needs to be lifted. Problem: other side is a retention pond of sorts. You have to find a way to raise the bridge to get across. Note: If you sucked at math, physics, and either The Legend of Zelda and/or Resident Evil puzzles, you'll be referencing a walkthrough constantly. The puzzles require the knowledge of weight, volume, buoyancy (for the puzzle above [your welcome]), and other things we neglected to care about in school.
Graphics: it's an original Xbox game, don't expect the greatest. Gameplay: Outside the puzzles, rather straightforward and fun (wait till you get the gravity gun). Replay value: ...depends. There's no difficulty setting, but you could go back and do everything again for self - confidence.
