"The second expansion pack for Wing Commander, The Secret Missions 2 adds a new narrative, new ships, more difficult missions, and two new wingmen.
The Tiger's Claw is in the Firekka System, whose native intelligent lifeforms (the bird-like Firekkans) are negotiating to join the Terran Confederation. Tensions are high, and will only get higher. There is an unusual Kilrathi presence in the area, including their upgraded Dralthi II and ships that have never been seen before: the Hhriss-class heavy fighter and the Snakeir-class heavy carrier."
