The Initiation Set box is both a complete game for 2 players and an introduction to the rules of AT-43. The White Stars forces face, over several missions, the terrifying Therian aliens on one of their Factory-planets. These scenarios allow you to get acquainted with the basics of the game in a simplified form at first, and then step by step into strategic depth. The box contains all the necessary material for two players to play the six missions of the handbook.
