Since every one and their grand mum has played at least one iteration of CoD, you’ll be glad to know CoD 3 is no different, as far as gameplay mechanics go. You’ll come to terms with the brutalities of war through the eyes of four different soldiers from four different nationalities; American, British, Canadian and Polish, and you’ll have to overcome an insane amount of odds to survive World War II. The single player campaign roughly spans fourteen missions and along the way you’ll indulge in a plethora of missions like planting explosives, defending an area, sabotaging German tanks to simple reach from point A to point B, and even though they may sound pretty boring on paper, they’re pretty engrossing to play. Ever since Call of Duty 2, this series has done away with the conventional health bar. The more damage you take, the more the edges of the screen redden indicating that you need to get out of harms way ASAP. Take cover, regenerate your health and you’re good to go. Borrowing a bit from Valve’s Word War II mod, Day of Defeat, CoD 3 even allows you to lob an enemy grenade back where it came from; as long you have quick reflexes, that is.
Even though development has shifted hands, Treyarch aren’t exactly new to the series (since they’re the ones behind call of Duty: Big Red One) and all the characteristics you’ve come to expect from this franchise (stuff I mentioned in the first paragraph like intense firefights, scripted sequences and so on) can be found in this game. I mean take the very first level for example; you’re in a truck making your way to the battlefield with your fellow soldiers, talking, making jokes when *boom* your convoy is hit by a bomb sending it tumbling. You black out, only to be dragged to safety by your comrades and once you shake the haze off, you're way to the nearby cemetery, and that’s when you’re hit with the magnitude of the situation. Bodies are strewn all over the place, bullets are whizzing past you, left right and center, Allied as well as Axis soldiers are panicking, shouting, screaming and dying... its all very cool, very Call of Duty.
The Less situations of SixAxis shows that they were like some LAST minute Additions to the PS3 version onto make it a little worth while.
