Lock On: Modern Air Combat is the first true modern hardcore flight simulator since the days of Falcon 4.0 and a direct continuation of the Flanker (1.0/2.0) games. Players get to fly six different aircraft: Mig-29, SU-25, SU-27, SU-33, F-15 and A-10. Comprehensive training missions and wide range of single missions help to prepare to the campaign where the player either helps to stop the Russian invasion of Ukraine or advances it. Multiplayer offers head-to-head or a co-op mode through TCP/IP or locally on LAN.
The game was released with quite a number of flaws that were eventually addressed in the patches 1.01 and 1.02. After that, publisher Ubisoft no longer supported the development studio on additional work for the game. Eagle Dynamics took matters eventually in their own hands and released the expansion Lock-on: Flaming Cliffs (an updated re-release), but they had to call it "unofficial".
