In some of the later games you can shoot underwater - with a harppon. And there will be some evil scuba divers out to get you as well (human enemies become more common in the sequels).

TR2 also has a mini-expansion similar to Unifinished Business. The special feature in it is that finding all secrets in all levels unlocks a secret bonus level ;)
