The Legacy TC is for version 1.4/1.5. It has 6 levels and the file is 943KB in size. The file name is legacy.zip. It was released on July 23, 1998.

The Legacy TC has very plain textures, fair level design, and fair to good gameplay. The levels are small with lots of weapons, ammo, health, and aliens. Some of the aliens have different attacks, and some spawn more aliens when killed. One of the bosses slowly drifts towards you after he is killed like he still wants to get you. I had to save often to make it through this TC. I rate it as fair with 2 out of 5 stars.
