Pterodon was a game studio from Brno, officially founded in 1998 by Jarek Kolář and Michal Janáček, although Petr Vlček and Jaroslav Kolář had been making games together since 1993, such as Tajemství Oslího ostrova and 7 dní a 7 nocí. After the real-time strategy Hesperian Wars (1998) and the action game Flying Heroes (2000), the studio scored its biggest hit with Vietcong (2003), followed by Vietcong: Fist Alpha, Vietcong: Red Dawn and Vietcong 2 (2005). The team then joined Illusion Softworks (later 2K Czech).
