- Good gun in The Island mission
In the second mission, 'The Island', there will be a man under the second bridge with a FG42 scoped. That gun will get more ammunition every time you kill someone. The gun begins with 96 ammo remaining and you can kill about 150 people with it (not including melee). After completing that mission you will have the gun on the third mission, but you must save the gun through the third mission to get it in the fourth mission and so on.

- Scoped FG42 in The Mace mission
When you get to the part where you must keep the Nazis from the trenches, do not listen to the men. Go to the right and follow the path to find an FG42 scoped leaning on a crate.
