Today brings the release of Rudolf Kremers & Alex May’s ambient RTS title Eufloria (formerly known as Dyson) onto Steam and Direct2Drive PC platforms. The IGF finalist brings a single player campaign with 25 levels, a skirmish mode, and an additional unlockable mode with new graphics and tougher AI.

The game runs $20 and is available now, if you’d like to try out the game first you can check out the demo. If the $20 price tag runs a little high for your pockets, your best bet is to wait for a sale, as they’ve been known to happen with these digital distributor types.

Rudolf Kremers & Alex May, developers of the indie space exploration strategy title Eufloria have released a playable demo in front of the full game’s launch tomorrow, October 20. Offering a good portion of what’s available in the full game, the dev points out that the title has seen massive changes since the IGF version of the title (previously known as Dyson) was shown off.

The demo can be downloaded on the official site for the game, and remember: Steam is offering a pre-purchase sale of 25% off to those who buy before the game unlocks on the digital distribution hub; which happens to be less than 24 hours away so get on it.

Apple has sent an email out to developers announcing a big change in their rules on DLC and or in-app purchases that will certainly affect the way indie devs approach an iPhone release. Previously only applications that cost $0.99 minimum could release extra content, subscriptions and/or digital service as a post launch add-on to the title. Now they’re extending this courtesy to all free applications as well.

This will likely bring about a major shift in how the App store works. For one, it eliminates the need for a lite version of a game as a developer could simply release a reduced version of the game for free and those who are willing to pay for the full version will use in-app purchases to gain the rest of the content. Additionally, developers who already offer up their titles for free can now consider potentially creating extra content for their game at a later date and if it’s successful, potentially earning profit from it. Seemingly a huge benefit for indie developers and their approach to launching their work on the mobile platform.

Soldak Entertainment has released a new update for their fantasy action RPG Depths of Peril, now available for download and on Steam. The patch brings the game to v1.015, adding several fixes, tweaks and improvements to the game.

Highlights include a tweak that allows for the player to give food/potions to people from other covenants when adventuring together, fixing some issues with spell mastery and reducing the difficulty of the kidnapping quest.

Steam users simply need to restart the client to apply the update, those who purchased else where can download the patch from GamersHell, an updated demo has been released as well.

Positech has released the latest beta version of their upcoming space simulation title Gratuitous Space Battles, now available on Impulse.

Celsius Game Studios, the work of one-man team Colin Walsh, released Chromodyne into the App Store on October 15. Although it is priced at $1.99, it is on sale currently for $0.99 cents to celebrate its release. I will provide a description of the game, but also have to commend Walsh on his creativity and use of humor.

“Gameplay is a twist on the traditional match-three style gameplay, with 5 concentric rings made up of different colored shapes. You have to rotate the rings and line up 3 or more of the same color and shape in a line going towards the center in order to clean up the MESS and add to your score” says the website. And I have to admit, it sounds pretty interesting. The story is that you’re the last to defend Earth from disaster by solving the match-3 puzzle and not allowing whatever object is heading towards it–be it an asteroid or comet–collide with the planet. To do this, you must utilize the Chromodyne, or the Quantum Chromodynamic Cyclotron, and you must utilize it well! For now, Celsius has two available game modes: Story and Survival; developer Colin Walsh promises more with perhaps a multiplayer and new story levels.

Rudolf Kremers & Alex May’s indie strategy title Eufloria has been listed on Steam and is now available for pre-purchase. The 2009 IGF finalist is being offered at 25% off to those who buy before it’s release next Tuesday.

The unique title features space exploration and conquest through “themes of plant growth and bio mechanical evolution.” Much of the content is procedurally generated making it so a level is never the same twice through.
