this trainer is not good because when i want use unlimited health it is giving for aliens too . can u tell me why it works like that??
This is because the same oppcode controls the player health and the AI health. Operating/Injecting this code will give the same effect to both of them.
Such routines are similar in Infernal, Serious Sam, Second Sight, etc.
The method I choose is to breakpoint the code, inject a code that compares the player's health pointer to the Code's register - which, if matches moves it to a high value/freezes it there.
