This is a lot worse than Gunslinger
Why don't the enemies take damage? After 6 shots they die; after six shots in the head they die. Not to mention that there are three at a time and the hiding ability is slower than a turtle.
This game is nearly impossible. Also, you should have a different level after every scene (just like in Gunslinger) so that the health bar will be full and you won't die in twenty seconds.
Not too much has been input to this game.
P.S.
Since this is a James Bond game, why don't the enemies die after only one shot? Think about it.
