And now we see the end of WON. "WON authentication servers will be phased out by the end of summer."

For those who have not tried steam yet you better start. Yes steam has some problems but very few and can be easily fixed. If you really hate Steam that much then stop playing now because in a few months you will not be able to play online anymore. So hold back your pride and do what you need to. Download steam cry a river and GET THE HELL OVER IT.

An update for CS:CZ and Counter-Strike has just been released. This release features three previously unreleased bonus missions for Condition Zero Deleted Scenes. Steam will update itself automatically when you restart. Here is a list of the additions:

COUNTER-STRIKE: CONDITION ZERO DELETED SCENES:

• Added previously unreleased missions Miami Heat, Truth in Chaos, and Run

COUNTER-STRIKE:

• Improved behavior of team_say


• Server prints team and player info in the console for chat messages


• Improved memory efficiency of hitbox animations to address intermittent server lag

Additionally, work is under way to transition players from WON to Steam. WON authentication servers will be phased out by the end of summer. If you have not already done so, you can download Steam here.
