On the Shortcut to the EXE, add the command -DEVMODE to it.
So, the link will point to something like
D:\Games\FarCry\bin32\FarCry.exe -devmode
And also have a look for the file called devmode.lua and then add this bit of code to the end of it:-
function ToggleGod()
if (not god) then
god=1;
else
god=1-god;
end
if (god==1) then
System:LogToConsole("God-Mode ON");
else
System:LogToConsole("God-Mode OFF");
end
end
Input:BindCommandToKey("#ToggleGod()","backspace",1);
Now, whenever you press BACKSPACE in the game, you will ENABLE / DISABLE GOD MODE
Also, if you press "O" or "P" you will get max ammo and max weapons.
Now, if oyu are given a weapon, it has no ammo in it, so select them both to get all the ammo for that weapon.
Erm...
As mussler said...
Google - "FarCry Cheats"
And reap the benefits.
Also, there is no harm in cheating... Sometimes it helps to keep[ a game alive if you are stuck in a certain place... I mean, I would rather cheat then stop playing the game just because I am stuck at a silly point, btu also cheating too much will also ruin the game too.
