This code makes it harder to complete the game because it keeps your life the same life from mission to mission (Example: if you finish one level with 50 percent you will start the next level with the same life.)

You will be taken to the photo gallery. Go through the gallery until you return to the main menu to have everything unlocked.
Full ammunition on new level
After beating the first level of a mission input the Infinite Ammunition code in the options menu. Then play the same level again with the code on. After you beat the level, when you get to the next level you'll have maximum ammunition. Repeat the code on levels that you have beaten, so when you go to the next new level you'll have enough ammo to last.
Hints
Take careful aim and go for head shots when you can.
Don't forget that grenades can do the trick when firearms can't.
A stealthy approach is best. Remember, you have a huge advantage if you see the enemy first.
How To Get A Flamethrower
When you get to mission 7, on the first level on the mission, there is a guy who's hiding. When you find him he will have a flamethrower. Kill this guy and you will have the flamethrower.
