Project Igi 1 All Missions Unlock -

For users uncomfortable with hex editing, third-party save unlockers exist. These executables patch the .sav file automatically.

Recommended approach (from community archives):

⚠️ Security note: Always scan third-party tools with antivirus software before execution.

Project I.G.I. (2000) by Innerloop Studios does not feature a native level-select menu upon starting a new game. Missions are designed to be played sequentially, with progress saved via profile-based checkpoint files. Unlocking all 14 missions requires either completing the game legitimately or manually modifying the game’s profile/save data. project igi 1 all missions unlock

map missionXX

Replace XX with the mission number from 01 to 14.

The only intended way to unlock all missions is to complete each mission sequentially. Upon finishing Mission 15 (“Return to the Base”), all missions become accessible from the main menu’s “Select Mission” option. This is the “clean” method but requires beating the game’s notoriously unfair final section—a helicopter battle with limited ammo and no checkpoints. For most players looking for a quick unlock, this is impractical.

The game stores mission progress in a binary file, e.g. savegame.sav or profile.sav.
By modifying a single byte at a known offset, all missions become selectable. For users uncomfortable with hex editing, third-party save

Example hex patch (for profile data):

Python script to unlock all missions:

import os
def unlock_all_missions():
save_path = os.path.expanduser("~\Documents\Project IGI\SaveGame.sav")
if not os.path.exists(save_path):
save_path = ".\SaveGame.sav"  # fallback to game folder ⚠️ Security note : Always scan third-party tools
with open(save_path, "r+b") as f:
    data = bytearray(f.read())
    # Offset 0x2C: mission completion flags (1 byte per mission? No – bitfield)
    # Actually, in IGI: offset 0x34 is mission progress byte
    data[0x34] = 0xFF  # All missions done
    # Recalculate simple XOR checksum (byte at offset 0x00)
    checksum = 0
    for i in range(1, len(data)):
        checksum ^= data[i]
    data[0x00] = checksum
    f.seek(0)
    f.write(data)
print("All missions unlocked!")
