An Add-on can be a group of additional levels or other game content like outfits. In Tomb Raider it is commonly used for the former.
Add-on Level Sets
To date there are five add-on level sets in the Tomb Raider Games; one for Tomb Raider, one for Tomb Raider II, one for Tomb Raider III and two for Tomb Raider Underworld. The add-ons for Tomb Raider and Tomb Raider 2 can be downloaded and played with the CD but The Lost Artifact is an independant game.
