How the impossible geometry of 'Tomb Raider III''s UFO level was made

"Tomb Raider" celebrates its 30th anniversary this month.

While many remember the iconic T-Rex or locking Winston the Butler in the freezer, many forget about the UFO in 1998’s "Tomb Raider III"; a mysterious alien craft that worked a lot like Doctor Who ’s TARDIS.

Coming off the back of the hugely successful "Tomb Raider 2", developer Core Design had big plans for the third entry, including kayaking, those iconic London levels, and, of course, a level featuring a UFO in Area 51.

Although it looked small on the outside, the UFO featured multiple floors for players to explore as they searched for a vital artifact, all as enemies swarmed in.

Now, I'm something of a Tomb Raider historian, and my upcoming book — " The Making of Tomb Raider: 1997-2000 " (available from October 30) — goes into detail about the making of "Tomb Raider III", "Tomb Raider IV", and other games in the series during those three years.

While writing the book, I spoke to level designer Richard Morton about how the physics-defying UFO was made and how shows like " The X-Files " inspired him and the team.

After completing India, you can choose between London, South Pacific, and Nevada to collect the other artifacts before reaching the final section in Antarctica.

Richard Morton was one of the designers for "Tomb Raider III", who took on South Pacific and some of Nevada, a location that Neal Boyd had already begun work on before he moved to "Project Eden".

Eventually, Lara would find herself in Area 51, with the final part of the level taking place in a UFO that houses the artifact she seeks.

“Area 51 was a bit of a team effort,” reveals Morton.

“The part where the rocket launches, Neal did a lot of that stuff.

So much of that level is his work, as well as some of the other routes.

Andy Sandham helped in finishing off that level, too.
