So, first off, what is stealth? Stealth is sneakily taking out opponents so that others don't see you, it's the opposite of charging into a building guns blazing and firing all over the place without a silencer. The intent of this guide is to teach you how to be stealthy and do it well. One thing important to keep in mind is that Call of Duty 4 is a game of preference. While I say this many times in the guide, I want to make sure you remember. Just because I use MP5 silenced doesn’t mean you should, for instance. You might like it, but if you simply love the P90 and can’t stand the MP5, then smack a silencer on it and knock yourself out. So read on, I hope this guide helps you, but remember to keep in mind: suit yourself!
