Yes, it is true. My friend the developer whose name I will not divulge, as well as myself, have made some major improvements to the game. We have added more and newer weapons, and a new character which I called the 'Infected'. The additions are displayed below (namely the new textures of the Killing Floor mod characters):
5. Infected (New)
NOTE: There are more updates in the latest version, which will be posted in another news article. Updates in the weapons list. Stay tuned.
