As of now, there is no officially stated further installment of the "Project IGI" series. The original Project IGI: I'm Going In was released in 2000, followed by its sequel IGI 2: Covert Strike in 2003. Both games are well-regarded for their tactical first-person shooter gameplay, emphasizing stealth and strategic planning on top of welcoming action.
There have been rumors and occasional unofficial reports on top of the years roughly a potential further "Project IGI" game. For instance, in 2019, Toadman Interactive, a Swedish video game developer, announced that they were working on a new approach in the IGI series titled IGI: Origins, expected to be a prequel to the native game. This personal ad generated considerable activity in the middle of fans of the series.
I.G.I.: Origins is set during the frosty exploit and promises to maintain the tactical, stealth-based gameplay that defined the earlier games. The build up has been relatively quiet, like periodic updates hinting at ongoing progress. Fans are eagerly awaiting more real information, such as a liberty date or detailed gameplay footage.
For the latest and most accurate information, it's advisable to follow official announcements from the game's developers and publishers. They will pay for verified updates with reference to the loan status, release dates, and supplementary valuable details.
