Elite Force II theoretically has 8 Information Geathering Missions, all these IGMs are aboard the USS Enterprise E.
The 5th IG-Mission has been deleted, I belive it was suppose to take place at the Attrexian Colony(Mission 7) but the level named m7l3-attrexian_colony does not exist.

You can find indications for this inside the following level script on line 134:

On one level in Elite Force II two spawner for Hostile aliens are target named "thx1138". THX 1138 is the name of a science fiction film directed by George Lucas

Usually target names do have the prefix t followed by a number, like t1, t2 and so on, but that target name does have two extra letters in in it, this rules out an accident.

There was a forth map, named m2l3-sfa, featuring another Starfleet Academy mission, but we have no information about it other than those from the scripts.

The Developer had plans for a race, where the player as Munro has to win against Cadets. Some Sound-files for this are still in the game.

Indications for further plans for a objective where the player had to look for a Character named Porter, which was then suppose to repair the Turbolift, can still be found in the level scripts. The room where the player would have to pickup a spare-part is also still accessible in the level m2l1-sfa.
