The Tactical Game uses a sophisticated Al system to control non-player forces. The system will adapt to your tactics by learning from its actions. This adaptation process occurs after each Tactical Game is played. The computer analyses an experience data file in order to update its decision matrices. The Al does not cheat (ie it has no privileged information or abilities beyond that of a human player). The data files for the Al are not stored as part of a saved game, they are continually updated. You can exchange the files with other X-COM players in order to experience different tactics from the Al player. Ensure that you exchange all three of the relevant files that are located within the TACDATA subdirectory.
