I just finished this game last night and I found the most helpfull thing to me was to hide behind walls not behind then wooden crates because they can blow up I also found that misssion 5 is the hardest misson right at the ebnd happy gameing
Best way I've found to get past the clusters of Wehrmacht guarding the main section of Nijmegen bridge is going down the right side, along the rail. It has the effect of cutting down the angle from the snipers above. As you approach the small guardhouse, crouch down, and eliminate the soldier in the guard house with the Gewehr 43 (sniper rifle), then eliminate the 1 or 2 others nearby. Proceed crouched along that rail, you'll come upon a wrecked vehicle (just about the point where you see that message indicating "take the ladder to the top." Keep inching forward along the rail until you can see the machine gun on the far side of the bridge (your left), and can just see all of the (visible) soldier that's manning it. Aim your sniper rifle, and blast him. Key point: don't keep the aim on that one point, other soldiers will appear straight ahead of you, so place your screen so you can still see that part of the bridge. Just aim at the machine gun when another soldier comes over to man it. If the Germans mount a major (2 or more) men straight to your front, crawl back a bit, to get out of the machine gun's line of fire. It's also a good idea to nail the snipers above you, as well. There's usually one on the catwalk, and one on top of the support pillar on your left, and they're a threat. You'll only see their shadows, and use their shots to trace them. Put the shadowy figures in the crosshairs, and shoot. Now, back to the machine gun. Once you've eliminated about 7 or 8 soldiers manning that far-side machine gun (you'll know when you don't see guys coming over to man it for a few minutes), switch to your MP40 submachine gun, and RUN past the pillars (stay to the right of them), then take out the soldier manning the machine gun on this side, and any more you find nearby. Collect all the ammo, and you're now free to move on to the next challenge (another machine gun nest), or hunt down those snipers and climb that ladder to eliminate the rest of the soldiers up there (if you're going for that gold star).
If u manage 2 creep up behind german soldiers as they hide behind walls zoom in on their hand...u can see it twitching..with the fingers pulling an invisible trigger!
Throw a grenade or stick grenade at sum germans and even tho 6 times out of 10 they will kick it away sumtimes they will:
1.Jump on it
2.Pick it up and run around
3.Pick it up and throw it back(!)
4.Fall over in an atempt to run away!
Just like a head shot... a groin shot can (suprisingly) kill instantly!!
On the 1st mission (D-Day) after u hav got into the trench..as u approach the room where the mounted machine gun is a german will use a dead body as a sheild and fire his gun at u...simply go bak where u wer and shoot him thru the window (he will still b firing at thin air!!)
In the level where u must photograph bleprints in various labs(clipping their wings) shoot the sciencists experiments twice and they will blow up.
