I have searched any games that are similar to Project I.G.I., but the games recommended by so many netizens are almost always the same ones, such as: Medal of Honor series, Delta Force series, Tom Clancy's Splinter Cell series, Metal Gear Solid series, GoldenEye 007 series, Tom Clancy's Rainbow Six, Line of Sight: Vietnam, Thief series, Desert Combat series, Battlefield series, Operation Flashpoint, Hitman series, Crysis, Far Cry, Tom Clancy's Ghost Recon series, and more. But finally I found a game that is much closer (can be regarded as a remake) to I.G.I. series - Beyond Enemy Lines.

Project I.G.I. (AKA: Sneaked, IGI is short for Institute for Geotactical Intelligence) is a series of tactical first-person shooter (FPS) PC game with realism elements and excellent graphics & sound effects design. In particular, the whole game comes with fantastic sandbox maps and playing methods, there are even dedicated servers built by fan players for online play. That's why it's so popular that it got numerous positive reviews from players around the world the time it came out (it has been 18 years as of this post, but AppNee is still willing to give it good praise).

Spying Around (I like to call it 'Project I.G.I. Flash version') is originally an action type of small online flash game. Due to its high gameplay, AppNee has re-packed it into an EXE file, so we can enjoy it anytime and anywhere.
