Cheat Engine: Health
-You search for 4-byte value: 100
Do this in the start of the game, then lose some health, then you change the Scan Type to: Smaller than...
And set the value to something like: 80
Then you should get some few addresses left
(Green ones are static, while black is dynamic)
Now, see which of the greens that are having the same value, and changes every-time you lose some health.
Then you will manage to find the correct one
FoV, you would need OllyDBG (It's the easiest)
But there's already tutorials about that
