After seeing his amateur mod become an unprecedented hit, Le joined Valve in 2000 to work on Counter-Strike in a professional capacity. According to IGN, Le worked on Counter-Strike 2 for a time, but the project "never really got off the ground" and was "put on the shelf."
Feeling unwanted pressure to work on another big project, Le left Valve on good terms, moved into his parents' basement, and began work on a project that would never see the light of day. Since then, he has secured funding from South Korean IT company FIX Korea to develop Tactical Intervention, his new take on the terrorists vs. counter-terrorists theme.
"I enjoyed Counter-Strike, but I wanted to have my own game," said Le. "I was never able to put in all the cool features I wanted because the people who played Counter-Strike would [complain] about all the changes. They liked the game as it is."
Tactical Intervention is reportedly based on a heavily-modified version of Valve's Source engine. The game will address many of the problems Le has with Counter-Strike, including lengthy rounds, camping, and sniper cheapness. Said Le: "I hated how powerful snipers were in Counter-Strike. They really unbalanced the game."
According to Le, the game is nearly complete and will enter beta-testing soon. A release is planned for later this year.
