10,000 Valve fans logged on to play Half-Life 2 en-masse in an attempt to make their campaign for more Half-Life information heard.
But that number is far less than the 50,000 users expected to make the gesture.
The A Call for Communication (Half-Life) Steam Group is lobbying Valve to release more information on the future of the Half-Life series - be that Half-Life 3 or Half-Life 2: Episode 3.
Still, the group managed to raise Half-Life 2's player figures during the event to 11th on Steam's listing, with in-game numbers up from the average 3000 active players to more than 13,000, Kotaku reports.
Group members have more than doubled since reaching 20,000 last week.
"The lack of communication between Valve and the Half-Life community has been a frustrating experience. While continued support for current and future products is greatly appreciated, fans of the Half-Life series have waited years for a word on when the franchise will return," the group's description reads.
Valve has yet to comment on the fan campaign. Did you take part? Was it fun?
