OpenTomb

OpenTomb is a game engine remake for the classic Tomb Raider games. The engine re-implements game 1-5 and preserves these classic action-adventures for posterity by providing a modern and free engine to run them on. Since I don't have the original games I can't try it and comment on how complete it is. But development seems very active, so if you have one of these games laying around you might want to give it a try.
