Aquaria has gone open source under the GPL! Now all four of the games that pledged to open in the Humble Indie Bundle are officially open source — the others are Lugaru, Gish, and Penumbra Overture. I am especially excited about the modding possibilities for Aquaria because of its excellent level editing tools. Here’s a video showing an early version of the editor:

Last month we reported on four indie games going open-source that were part of the pay-what-you-want "Humble Indie Bundle" after the developers experienced very favorable returns. The source-code to Aquaria has now been published with the source-code to the three other titles (Lugaru, Gish, and Penumbra Overture) already being available.

After the huge success of the Humble Indie Bundle, and the raise of over 1 Million Dollars in donations – the games in this “project” are “freeing their sources”.
After Lugaru and Penumbra Overture freed their sources, Gish is now following their example.
The source is under GPL and can be downloaded from here.

It has been in our minds for quite some time and now finally it has become reality: Penumbra:Overture and the HPL1 Engine are now open source!

Lugaru HD was a part of the Humble Indie Bundle which allowed users to pay whatever the want for some great cross-platform games. They said they will open-source the games if they reach 1,000,000 - which they did, so all the games are about to be released as open source.

Last week I talked about some the advantages of Free/Open Source software for us end users. Today developers speak on why they like to use FOSS; I received so many excellent responses that I have split this into two parts, and the second part will run tomorrow.

In the spirit of the Humble Indie Bundle, we have decided to release the source code to Lugaru! Our community has already made some great mods by editing the levels and graphics, but source code access will allow for much deeper modifications.

"So we have a few great Free Software gaming engines now, like DarkPlaces used in Nexuiz, Cube 2 used in Sauerbraten, Qfusion used in Warsow, soon id Tech 4 which is used in id Software's Quake 4, Doom 3, Enemy Territory: Quake Wars along with many others, and the HPL1 engine used in Frictional Games' "Penumbra: Overture".

The scary Penumbra game trilogy, has just recently been ported natively to GNU-Linux by the manufacturer, Frictional Games. The Penumbra games are first person survival horror and physics puzzle games which challenge the player to survive in a mine in Greenland which has been taken over by a monstrous thing.
