The Planets³ website has word that those who have preordered the open-world voxel-based RPG are now entitled to download the alpha version (thanks nin). Here's the news:

Today is a big day for the Planets³ project: the alpha version is now available!
For those of you who preordered a game license eligible for the alpha, you can download it here.

We wanted to surprise you with the alpha: you will be able to experiment a first preview of a randomly generated dungeon. The goal is to show you the science fiction RPG aspect of the game and a preview of our generation engine. We spent almost 5 months to develop all mechanisms required for this new feature. 5 months during which we had to remain silent, to prevent any spoil of this surprise until today.

Even if we are still far from what we will deliver for the final game, we hope that you will like this alpha content as much as we like it!

Talking about the story: the alpha is a prologue, the story take place 200 years before the facts that will be related in the game. This allow us to introduce 2 of the main species: the Humans and the Cognitrons. This alpha content will most certainly be used in the final game. So it was not a waste of time.

We leave it to you to discover the rest of the story by exploring this alpha content yourself.
