I accidentally posted the fail video for Penny vs. Sarge now there's a weird video with no video sorry! "Watch the whole video if you know what happens :)"
I know the easiest way to kill Sarge which no one would have ever imagined Walk slowly to the next level go outside the door then frequently come back again. The door will close and leave you outside. When sarge will come to kill you you can attack him from beging the door Try it
