Just think about it. The EZ tranquilizer gun does anything. It regains your stamina, it knocks out your enemy's, it has unlimited ammunition and it adds to your camouflage. I think this gun makes everything too easy. And on top of all of that, it has an unlimited silencer, unlike all the other tranquiliers in the game.

Really, what did you expect? It is called the EASY GUN. Just don't use it if you want a challenge.

I have been looking for a place to post this all day and have not succeeded. So I will post it here.

Well it is called the EZ gun. It also has a laser sight like the MGS2 guns instead of looking down the sights, and you can zoom in too. It's your choice if you want to use it though. I never earned it to use at harder difficulties.
