Half-Life 2

THE GOOD:
My favoutite FPS EVER.
Graphics are amazing. People look real, enemies look real, your surroundings look real.
The enemy and friend AI is brilliant, people dont just run blindly into the fray of battle, only to get mowed down by heavy fire. Instead they make descisions for themselves and usually use their enviroment to ensure their safety whilst attacking. Well, most of the time, anyway...
storyline is good (for an FPS) and parts of the game are actually scarey. You'll know what I mean when you get to Ravenholme... You end up jumping at the sound of Gordon's own footsteps and firing random shotgun blasts at rustling leaves that look vaguely like a headcrab.
The gameplay and controls havnt changed much, but one of the best new things is the gravity gun, which you get about 1/6 of the way through the game. Pick stuff up and blast it at enemies! And right at the end of the game, it gets even better! I wont say how...
And the final great feature is the fact that when you buy HL2, you get Counterstike Source, Half Life 2: Deathmatch and Codename Gordon (or something like that) as well.

THE BAD:
Not much to say here, apart from the sometimes dodgy descisions made by other charactors, the only fault with their otherwie perfect AI. My advice is: (in "entanglement" and "follow freeman!") send your squad away before going in to get rid of turret guns! They'll all die otherwise!
Another bad thing is that you'll need a supercomputer with the very latest graphics card to run this game properly.

SUMMARY:
In Half life 2, you once again play as Gordon Freeman, one of the survivors from the Black Mesa incident in HL1. The game starts with a weird scene in which you find yourself in a Combine (the evil people who look like helghast from killzone) controlled city, where little humans like you struggle to survive, oppressed and tortured by the ever present gun/buzz baton weilding guards. Soon, you are reunited with charactors from the last game, are given your trusty crowbar again, and told to travel back to black mesa. You are helped along the way by members of the human resistance against the combine, and attacked by a variety of enemies.
Landscapes vary from beach sands complete with the constant threat of Antlions, Lakes and rivers of Acid complete with the constant threat of a Zombie popping up with no warning, desolated cities complete with warring resistance and Combine troops, and the dark allyways of an infested town, and in all of these locations, the graphics are kickass.
You can even drive a couple of vehicles, including a hovercraft (with a very large gun attached) and a buggy thingy (with a slightly smaller gun attached).
Overall this game is near perfect. But you'll need a supercomputer with the latest in graphics technology to run it.
