If your not level 5 by the time you get to the middle of episode 2 then read this solution. But if you want to stay here to level 15 then read below! :)
Hello, if you want to get this Achievement by Episode 2
then follow this solution.
Now what I did was I kept on "taking down" the warrant target which gave me 500 points every time.
Now you can do this very easy on Episode 2
and it doesn't take you long at all. You can get 500 points in 10 seconds
I would say. But hey, if you want even more pull out your stun gun and stun the guys around you. But make sure you leave one alive to kill you
so you can re spawn at the checkpoint you will see in the below video.
There is NO need to reset checkpoints or restart the level
for this to work :).
It's as simple as that doesn't take you long at all and you get to unlock all the weapons to help you in the further episodes.
