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):
1. Bloat
2. Clot
3. Crawler
4. Gorefast
5. Infected (New)
6. Scrake
7. Siren
8. Stalker
NOTE: There are more updates in the latest version, which will be posted in another news article. Updates in the weapons list. Stay tuned.
Sad to see no one plays this anymore and that this hasn't been finished up. Keep it up, if you're still alive.
I still play 2.5... Even though no one joins... :(
