Doom³

The Good
The graphics engine is awesome. There's hardly anything original as far as visual effects are concerned, but it's definitely something never seen in a computer game before. The human heads and the lighting engine is particularly worth noting.

Level design is superb. While there's not much room for fantasy (most of the game takes place in a high-tech labyrinth filled with computers and other hardware equipment), there is a lot of high-quality architecture work, strategically positioned pentagrams, blood splatters, dead bodies, and some kind of spooky demonic protoplasm seeping through the walls. A short trip to Hell is a welcome break from steel and plastic, but I'm sure you'll be glad that you got out of there eventually - I was expecting a boatload of hell knights to drop on my head every moment.

Old foes are back, with only a couple missing; the weapons have been mostly redesigned, and their design and balance is completely different, but that's okay (BFG's here and it works the same, so I'm happy).

The Bad
Scares get old really quick; most annoying ones include an imp jumping at you soon as you open the door, and a steam jet blowing in your face as you pass by. There are a few good ones, but you'll be very unlikely to get scared as soon as ten hours into the game.

There is hardly anything that you haven't seen in Half-Life or System Shock 2. In fact, the game feels like a complete rip-off of that stellar pair. I know it probably won't bother a lot of people, but when similarities are so blatant, you start to get annoyed.

The game is so dark it's hampering the gameplay. Sure, a dark room here and there is cool and fun, but when it's dark ALL THE TIME, you throw up your arms in desperation. A flashlight is helpful, but not by much; besides you can't fire with a flashlight on. A common "close quarters encounter" means switching from flashlight to your primary gun, firing a few rounds in the dark, then turning on the flashlight to see if it's dead, and moving on. That darkness and repetitiveness annoys a LOT of people I know.

The Bottom Line
Get it if your computer can handle the graphics and if plagiarized gameplay doesn't bother you. If you want a scary shooter, look for System Shock 2 instead.
