From the website:
Bill and Chompski from Left 4 Dead 2 now in Dying Light.
Meet Bill and gnome Chompski. You already know them? That’s great because now they’re coming to Dying Light as a new playable model and a two-handed weapon. Download the new DLC to enjoy these iconic Left 4 Dead characters in Harran, and have the best of both worlds.
Enjoy!
I still remember spending a good deal of time sending Gnome Chompski to space in Half Life 2. Godspeed little fella, godspeed.
