Just some minor issues encountered while playing with trainer.
1) The fast kill ( F5 ) will causes players who get poisoned by snake to die immediately on second hit if they did not activate infinite health ( F1 ).
2) If player were killed when Infinite Health, the game will never ends.
3) The infinite item code makes weapon appears with 99 ammo but unfortunately, the weapon has limited ammo and it still retain its original number.
4) Saving games while playing Infinite Health will retain the infinite health throughout the whole game until players select a new game mode. Unfortunately, you can still get poisoned by snakes although you cannot take damage.
