What did Counter-Strike creator, Minh Le, do next? He decided to make a game called Tactical Intervention, according to this IGN piece.
Minh moved to South Korea in April 2008 after Counter-Strike 2 was "shelved," and was backed by a businessman to make the new title. The first shots are through the link.
It looks like super-speed CS with hostages.
"I wanted to make TI faster so people aren't waiting around as much between rounds," said Minh.
"The average round should be two minutes, maybe less, so people aren't waiting around as much."
Apparently Tactical Intervention will be going into beta "soon" and is likely to be released by the end of this year.
