About Semper Fidelis Alliance, from BoardGameGeek:

Game of battles with miniatures. Quick and easy rules to play immediately. The game comes with a book with the basic rules and lists of fighters. It is proposed as a cooperative game, in which different players (or only one) face an automated and undaunted enemy that does not know surrender. -description from the designer
