In Let’s Kill Jeff The Killer Ch3, you need to find eight lanterns and escape from an abandoned building. Sounds easy, right? Not really, because Jeff the Killer and his eight nasty rats are out to tear you from limb to limb. Don’t worry, you can choose to play either Normal mode or Tough Mode. 

The former lets you choose between three weapons, namely the M9, RPK, and a shotgun. Whereas in the latter, you will only have to use a pair of brass knuckles. Both modes are fun, but if you’re just starting out, it’s recommended to play the game in normal mode.
