The Counter-Strike mod for Half-Life came out in 1999, but it wasn't Lee's first project as he turned 21 at the time. He started doing mods back in 1996: he developed tools to make projects on the Quake engine. In 1997, Lee released the Navy Seals mod, which already strongly resembled the game that would make Gooseman world-famous.

A year later, Min Li teamed up with Jess Cliff (the second "father" of CS, who would later work on CS:GO). Together they released the Action Quake 2 mod. In terms of gameplay, it did not resemble Counter-Strike a bit: the game was too fast and arcade. But visually - more like: recognizable weapons, compact maps and textures (for example, very similar buildings are used on the Assault map).

A few days after the release of Action Quake 2, Half-Life was released. A year later, the Counter-Strike mod came out. Two years after that, Valve will buy the rights to it, and Lee and Cliff will enter the company's staff to improve the shooter and work on new games in the series.

Lee worked remotely for Valve: he mainly worked on the classic Counter-Strike, but also took a little part in the development of Counter-Strike: Condition Zero. Gooseman's main project was supposed to be Counter-Strike 2, a game on the Source engine that Valve had high hopes for, but ...

According to Lee, it took him a long time to get used to Source. He thought about the concept of the game for a long time, but in the end, according to his own estimates, he managed to make it only 10-15%. He created several models of weapons, characters and levels - and that's it. While working on the project, Lee felt a great responsibility: it was necessary to come up with something new, but at the same time retain everything that the fans loved the shooter for. The stress was too great, so in 2006 he abandoned the development of the game and left Valve.

For two years, Lee worked independently on the "spiritual heir to Counter-Strike." There he developed ideas that did not fit into the concept of CS. But he ran out of money, so in 2008, Lee found a new employer - the Korean gaming company FIX Korea. There he developed his game for five years - the network shooter Tactical Intervention, which used the same Source engine. The end result is Counter-Strike 2 as Lee envisioned it.

Dogs, car chases, the use of hostages as human shields - all of this bore little resemblance to Counter-Strike. Tactical Intervention failed due to outdated graphics and boring gameplay.

Shortly after the release of TI, Lee left FIX Korea and joined Facepunch Studios, where he worked on the online survival sim Rust. At that time, the game was already in early access on the Steam platform, so Lee's contribution to this game cannot be called great. In 2018, the shooter left early access, and Gooseman left the studio.

He has now returned to Korea and plans to work for Pearl Abyss. Apparently, Lee's new game will be very different from the usual shooters like Counter-Strike or "royal battles" in the spirit of PUBG or Fortnite. In a 2016 interview, Lee said that shooters in the usual sense have already reached their peak - there is simply nowhere to improve them. As an example, he cites Counter-Strike, Overwatch and Battlefield, in which, it would seem, everything has already been implemented. He also mentioned that he wants to try himself in other genres, so we expect something new and unusual from him. We hope that he will be remembered not only for Counter-Strike.
