After showing off exactly what they can do by apparently fixing major bugs in the CS:S game engine the guys over at zBlock have released a public beta so you can test it out for yourselves.

It's been hailed as the saviour of source by some people due to the fact that when enabled it makes 'Bunnyhopping' 'Crouchbugging' and 'Superboosting' impossible, this makes for much fairer game play both online and on LAN events. Along with this multiple bugs within the game have been fixed.

zBlock developer j3di had the following to say on the zBlock website

"zBlock 4.4 RC1 is now available for public beta testing. You can download it via "rcon zb_update beta" if you use zBlock 4.3. You will need to use this command twice, once to check for the beta update then again to download, you will then need to restart the server. Auto-Updating from older versions will not work."

Full details of the fixes this latest update contains are below:
