Tomb Raider 3

Tomb Raider III opens millions of years ago, when a meteoroid survived the plunge through the Earth's atmosphere, impacting the then-warm climate of Antarctica. The first people to discover this land were a tribe of Polynesians. Despite the now-freezing conditions, there was an abnormal abundance of life and the tribe settled, worshipping the meteorite crater for the powers it appeared to hold and then forged parts of the meteorite into four artefacts. Generations later, though, catastrophic events forced them to flee in terror. Today, the same area is being excavated by the research company RX Tech, headed by the eccentric Scotsman Dr. Willard. The team is picking up unusual readings from the meteorite's impact zone. Soon after they uncover the body of a sailor from Charles Darwin's voyage on the Beagle. It seems a few of his sailors had explored the interior of the crater.
Following a story from one of the sailors' journal, RX Tech have started to take a particular interest in not only the crater area, but other parts of the globe where the sailors travelled to... and therein died. One of these places is India - where Lara Croft is currently searching for the legendary Infada artefact. Unaware of its true history, she only knows that in local beliefs it was supposed to hold great powers and has been revered by tribes there throughout the years. After retrieving the Infada stone she meets Dr. Willard on a sail boat who informs her of the story of Darwin's sailors as well as the existence of the other three Meteorite Artefacts. They are found in London, the South Pacific and in Nevada.
Once she has collected all four pieces Lara travels to Antarctica where she meets Dr. Willard and learns of his true intentions. Apparently each artefact individually can cause a significant rise in the number of genes within a persons DNA thus causing a mutation. However when all four are combined with the meteorite they can rapidly accelerate human evolution. After testing on a few of his employees he steals the artefacts from Lara and heads towards the Meteorite Cavern where he transforms into a large immortal arachnid that Lara defeats by reversing the process. Once he is dead Lara escapes and heads for home.
