Avega let us know at the forum that he's made a mod for Fallout that gives recruitable NPC's (bar Dogmeat) some new abilities and options to set combat tactics, also, we learn that he's made an unofficial patch for the game, to be used in conjunction with the mod. Both files are available from the NMA downloads section.
