From that day on, Jack became a regular visitor to IGIMods.com, always on the lookout for new and exciting mods to enhance his gaming experience. And he never forgot the all-weapons mod that had started it all, a mod that had breathed new life into a game he thought he knew like the back of his hand.
Some versions of the mod even unlock "hidden" or rare weapons not standardly available in the mission selection. Installation & Download
I found a working mod for Project IGI 1 that unlocks all weapons in the inventory. No more sneaking around with just the silenced Glock! This mod allows you to select any weapon, including the Minigun and Spas-12, right from the start of the mission.
