If you've been wanting to create your own playable levels using the Tomb Raider Level Editor but didn't know where to start, there is now a beginners' group on Facebook that can help. My friend Eldin, a long-time TR fan, recently started this online community, which is open to anyone with an interest in learning to use the editing tools.
To join the group you'll need a Facebook account. Then just visit the Tomb Raider Level Editor group page and click the 'Ask to Join Group' link. If you have questions before joining, you can contact Eldin and the other members through my page.
The Tomb Raider Level Editor is based on the Last Revelation game engine and was released in 2000 along with the Tomb Raider Chronicles game. Since then, players have designed thousands of levels and created dozens of tools and utilities to make level creation easier and more interesting.
George Maciver, webmaster of Skribblers.com, wrote a great introduction to the editor for this blog a while back. You can find it here: "Living in Lara's World: The Tomb Raider Level Editor".
If you don't own the original Chronicles game—or have the PlayStation version, which does not include the editor—it's available as a free download for Windows or Macintosh. You can find the program, instruction manual and links to other Level Editor resources on my Tomb Raider Level Editor page.
