Each time you change soldiers, you need to press the key for the attribute you want to change. Let's say you increase the aim on your heavy and now you want to increase the aim on your sniper. You will click the arrow in whatever direction you need to scroll. Once you have located the soldier, you will press the num / key. Then you can increase or decrease as needed.
If you do not press the attribute key again, it will stay "locked" on the last soldier you used it on.
For the trainer, I noticed during combat mission that you select the character, press the hotkey for the stat you want to boost (say health for example, Numpad 1) and then press either Numpad + or - or *. Then press F1 while the character is still selected to see amazing results....UBER SOLDIER Now, if I could just get the money to work... will probably just resort to hex editing I guess
I'm gonna check something the hardway. Is it possible there was a problem with the whole pre-load option of the game versus those who downloaded it when it was finally released. So I'm downloading again and will know for sure in 2 hours.
Windows 7 64bit, running trainer as admin, and game as admin (via steam), the install is the pre-load version. Money only worked once as demonstrated in the video. After loading a new game, it stopped functioning and hasn't worked since. Tried rebooting, admin on both again, nada. No dice. Everything else works great though.
