Numpad 3: No Reload - press this key to give the CURRENTLY selected weapon the ability
to shoot non-stop. If you swap weapons, turn this off and on again to make
it work for the new weapon.
this was described in the notes which comes with the trainer.
OR you can try one of the other trainers that are out for this game... OOOPS! there aren't any... because this game SUCKS to make a trainer for due to the protections built into it (and also due to the fact that it hasn't been cracked).
