You can do it with code injection which may be the harder but more sophisticated way, or You can do it by finding a pointer for Your health only and freeze Your health.

I suggest to beat the Cheat Engine tutorial to see how to find pointers.
If You need some help, You can find my tutorials and videos here:

If You choose code injection to solve the issue, try to find a code which is accessing to Your health only so You can modify it to give max health for You. I am not sure if there is a code like that in this game, because I did not hack it. It is just a general advice.

Geri i saw this on your forum
For a fine example on how to use the stack, compare, conditional jumps and mov, I will describe how did I make a "God Mode" for my soldiers in an RTS game, Warhammer: Mark of Chaos.

First of all You need to search for a soldier's health and check which code is writing to the address of health. However, this code is changing all of the soldiers' health in the game, including the enemy soldiers. So if You just turn off this code, everyone will be invincible. That would not be useful.

The code which is changing the health is the following:
008d0f08 - d9 56 04 - fst dword ptr [esi+04]

If You look in the memory browser, You will realise that the soldier's data structure is very simple in this game. As You can see it in the code, the health is stored on esi+04. The maximum health of the unit is 4 bytes later, so it is on esi+08. One more information: if the value before the health (esi) is 0, then the unit is Your unit. If it is not, then an enemy unit.

So the data structure is the following:
[esi] = player ID, if it is 0, then the unit is Yours
[esi+04] = health
[esi+08] = max health


With these information, we can plan our script now. It should do the following:
Check if the unit is Your unit.
If it is Your unit, change the healt to the maximum health.

The script will look like this:

fst dword ptr [esi+04] //original code which is changing health
pushad //save the registers
pushfd //save the flags
cmp [esi],0 //check if the player ID is equal to 0
jne +6 //if it is not 0, the program will skip the next 2 lines
mov eax,[esi+08] //copy the value of max health to eax
mov [esi+04],eax //copy eax to the health, so max health=health
popfd //load flags
popad //load registers


can you explain how to do that on other games, call of duty 4 ,gta san andreas ..... pls , i dont understand that very well,can you make some tutorial of any game using this script pls , i know lot of things in cheat engine i completed 9 tutorials easy i know lot of stuff"s but this i dont know the best ((((sorry bad english)))))) and pls make video tutorial !!
