You guys should really check this game out. It's a free game made by some students at the DigiPen Institute (the same place where Narbacular Drop was made, which later became Portal). This game is a mix of Marble Madness, Pinball, those old fashioned wooden labyrinth games with the steel marble, and a 3rd person hack n slash. The game is fantastic! The graphics are beautiful and the gameplay is really original. The only downside is that it's unfortunately a little short (but what can you expect, it's a student project and it's free).

Terra uses Valve's Source engine, so you will need Steam to play it and the installer will put the game into your Steam library as well as download the relevant Source tools.

Nifty, downloading.

Let me know what you think once you try it. I really liked this one.

Unfortunately there are several steps required to get a Source mod listed on Steam; many mods are in a completed state for quite a while before they get listed.

downloading, looks nice.

EDIT> downloaded, tested. What a nice little game! graphics are cute and even if the controls are a little tricky at first, you get accustomed to them quite quickly. Thanks again for the link!

Thanks for spreading the world JT.

:)

For those who wanna see before they download.
