This is my favourite online FPS, its definately worth checking out

User Rating: 9.7 | Day of Defeat: Source PC
Day of Defeat was origionally a mod for half life, valve rcently relesead the source version which surpasses even the origional for several reasons.
New maps are added for this game constantly, official and user made, very recently a new game mode was added too, and there are also plans to add the british forces into the game, like in the origional.

The gamespot reveiew is out of date really, origionally there only about 4 maps for the game, now there are upward of a hundred if you look for them, if you dont have a map, fear not simply click on the game playing the map and it will be downloaded while the game loads, this doesnt even take that long.

STORY - none, this is entirely online

GAMEPLAY - this gameplay is fast, gritty and requires alot of skill to truely excell at it, the different class system is similar to the battlefield games.
There are NO vehicles in this game at all, almost all of the official maps in the game are set in small, wartorn french villages so the level design is perfect for infantry battles and intense firefights. The 2 sides (axis and allies) are perfectly balanced in both weapons and locations making this a very fair game. Teamwork is a large part of this game, communication through headsets is vital for success.
The weapons in this game look and sound great, they just have that 'umpf' that is lacking in so many games, and with the addition of blood in the game you get a real satisfaction everytime you kill someone in this game (good enough to bring out the psycho in all of us) Turn your bass up and just feel every shot fired.

GRAPHICS - the game uses the famous source engine, used in half life 2 so the graphics and phisics are superb and not too taxing on your pc. But i dont care about graphics at all.

VALUE - excellent, very replayable game, maps added so often you'll never run out, updates aplenty. My game came free with CS: source anyway.

STABILITY - i have never had a major problem with this game, it has never crashed the lag is non existant, and my pc isnt great, i am so impressed by how smoothly it runs while battlefield 2 crashes on pretty much everyone everyday (bf2 - also great game) the loading times are really fast too.

PROS - quick loading times, solid gameplay, awesome sound, tonnes of maps, wonderfully violent, realist ic weapons and damages

CONS - no vehicles (i prefer it but many will really miss them)

all in all a truely A grade game that takes alot of criticism but wrongfully so in my opinion, if you are unsure whether you want to get this game, valve often hold 'free weekends' to encourage new players to buy it.
