This is a very nice game about the American 82nd and 101st Airborne divisions of WWII. The spawning system involves jumping about of a plane and parachuting down on your enemies, which is rather exciting. Another thing worthy of note is that during the campaign, you face Tiger I tanks. You know, the killing machines that were feared by Sherman tanks everywhere. These monsters are not at all unwilling to lob their 88mm HE rounds directly at your face, which, quite fittingly, is an insta-kill. The only way to retaliate against them is with Gammon grenades or an AT Rifle.
The choice of weapons is also pleasing, and their roles in combat are well-shown. As in, machine guns are deadly to both you and your foe, and sniping with any old weapon simply won't work. Grenades also show their role both as a surpression weapon and a room-clearing device.
One of the better brand-name first-person shooters that has a surprisingly high amount of realism, definately look into this one.
