Project IGI is a first-person shooter game that stands out from its contemporaries due to its unique gameplay. Immediately after the release, the game received favorable reviews from the worldwide media, and although it failed to become a million-seller, it did manage to become one of the few games from the early 2000s that has achieved cult status for its technical solutions and the impact in had in game development over the next several years. Even though it innovated in many fields, the game was also criticized for the outright lack of multiplayer, weak enemy AI, and the number of technical issues that affected the stability of the game.
The driving force that fueled these technical innovations came from the use of the proprietary game engine that developers at Innerloop created for the use in their 1997’s combat flight simulator game Joint Strike Fighter.
