Valve has released an update to the Left 4 Dead demo, and the exploit to play as Infected no longer works. The update notes:
- Tuned matchmaking to provide better search results
- Added UI to host a game on a local server
- Improvements and performance optimizations to network layer
- Improved handling of unsupported graphics hardware
- Fixed a rare crash when kicking people from lobby
- Fixes for demo exploits
- Localization fixes
- Increase automatic port range when running a Linux dedicated server with -fork
I opened up the demo and most cheats still work (z_add, noclip, z_spawn, etc) but the command ent_fire !self setteam 3 which used to allow you to play as Infected no longer does anything.
Meh. It’s really hard to complain when there’s only a week until the full game is released. It was a pretty buggy cheat and it’s easy to understand why Valve would do this.
