The best single player FPS out there. Better than MOHAA!
The graphics are a little disappointing, considering the time of release. But the experience can still be thrilling and the choppy graphics could be actually enhancing the effect of a WWII fighter. Compared to MOHAA (Medal of Honor Allied Assault), the graphics aren't much improved, so if you didn't like MOHAA, you most likely wouldn't like COD2.
Sound: 10/10
The sound's great, complete with all the explosions, surround sound, and stutter of gunfire. Very realistic and no lag. No complaints in this department.
Gameplay: 10/10
Now here's where COD2 excels. It's objectives usually allow a few ways to tackle a problem, especially if it's a large battleground. So instead of games such as MOHAA, where there's only 1 single way to complete a stage, COD2 offers slight deviations from the "original" plan. Another great feature of COD2 is the ability for you to pick up fallen comrades or enemies' weapons. So if you don't like the weapons you're assigned, all you have to do is kill an enemy sniper and take his gun! Also, the guns are very different and have special traits, so this keeps the fun going after the initial excitement wears off.
The bad
There is one annoying thing about COD2 that isn't too realistic. If you keep on talking to your teamates at a position where there is continuous enemy fire, such as a blockade or mounted machine gun, your team will eventually run into the line of fire. Normally, you'd think you're left alone or only with a secondary backup team. However, you'd find that there is an UNLIMITED number of reinforcements!!! I find that this takes the realism away somewhat.
The good
There are very different difficulty settings. This allows new players to really get the hang of the game, and also give a challenge to the best FPS player out there.
