The lights are on
Basically your'e thinking the only way to get this is to be the
best control/video game freak ever.
Guess what? You're wrong.
All you need to do if you want to get this achievement is right
1. The first step is to find the pistol that best suits you.
The pistol is your best friend for you in order to get this achievement. What I
like to do is try not to get a very powerful weapon. Go for something smaller
and with a faster fire rate and accuracy. I would either go for the USP.45
or the G18.
2. Pick the assault rifle that feels right to use because once you're
out of bullets on your pistol (if you use the pistol first) you're going
to have to rely on your assault rifle.
3. Know your enemy. What I mean by this is that you should
memorize the positions of the friendly/non-friendly cardboard cutouts.
Of course you might be thinking that you will never memorize that.
but it's easy as 1-2-3.
Follow these steps and you'll be on your way to this achievement...bleep...bloop...lol.
