A high number of tutorials will quickly enable you to become familiar with the features. An exhaustive list of the over 100 objects (including cloners, traps, rocks, skulls, bombs, lasers, gems and other, even more interesting devices) explains in full detail the properties of each diversion. SubTerra offers a user-friendly level editor. You can plan all sorts of schemes, itineraries and surprises, setting your creativity at work. Then have other players try and solve the levels by taking part in the yearly contest for the best homebrew level! The jury, formed by Radiant, collaborators and friends, will reward a free Crystal Shard game to the winner. And even if you don't win, enjoy the pride of having your levels included in the free expansion pack!

So far, more than 250 levels can be downloaded but they can be counted up as twice as many since you can play them on both Easy Mode and Hard Mode (this last mode having some time restrictions or a higher score required). Surprises do not end here: there are zounds of secrets! The Hall of Fame gives you the channel to tell the world how good you are!

Exciting and relaxing at the same time, SubTerra is guaranteed to provide you with many hours of fine entertainment, enhancing your ability to project, to solve problems, as well as create your own. The game was produced by Crystal Shard, a small Dutch firm. It's now being sold on a "name-your-price" basis. No reason not to try it!
