DEMO: This game was finished in 2007 and you can download the demo and try it out right now at -- the game is name your price with a $1.75 minimum, and the demo contains one-third of the entire game (which is around six hours of gameplay). Most likely, people who have purchased this on my site before it is released on Steam will get Steam keys if it passes through Greenlight.

Is there anything you would give up everything to defend? Immortal Defense is a story-driven, strategic tower defense game in which you give up life and your family forever to traverse pathspace and defend your home world from destruction. Becoming intangible and immortal, you defend your planet through the generations, eventually forming a friendship with your granddaughter. The story line takes place over millions of years, as the universe drastically changes and you remain immortal.

Immortal Defense was acclaimed 2007 Indie Strategy Game of the Year by, and praised by many others for its storytelling and unique twist on the strategy genre. It's considered a classic indie game and was one of the first successful commercial tower defense games. The game has sold thousands of copies, mostly on its own website, so we are confident it can do well on steam within the tower defense niche. Here are some excerpts from reviews the game has received:

I typically hate the tower defense genre (Plants vs Zombies and Lock's Quest notwithstanding), and was thus truly surprised to see myself power through all one hundred levels of Immortal Defense. Granted, I began to suck near the last act of the game and may have lowered the difficulty a bit (and by 'a bit', I may mean 'all the way') in order to see the rest of the story, but I still had some serious fun with Immortal Defense. Perhaps you will, too. - Anthony Burch, Destructoid

The brief text sequences between levels carries the story--to fight in 'pathspace,' you have foregone your body and normal existence, and the concerns of the people who are sworn to defend seem increasingly irrelevant to you, in this very different existence. I typically think this kind of backstory is irrelevant (and often poorly written), but here it's almost haunting--nicely done. - Greg Costikyan

Note that this game's demo is BEEFY. 30 some levels out of the full game's 90-some with access to all 10 difficulty levels. You could probably squeeze 3-5 hours out of this demo if so inclined. -

I’m not proposing the game would be better in the first person, Thornton clearly intended me to have these intense moments of reflection while playing. But at the same time, I’m not sure what to make of a game that induces them by blasting me out of the experience. Should a video game ever do this? I don’t really know. -

Immortal Defense is only a game, but it touches many quite serious subjects - like protecting the family, barrier between gratitude and worship, limits of responsibility, loneliness, memory and love. Actually the game seems like a stylish metaphor of human life, gameplay aside. - Thomas Grochowiak, of MoaCube

I think this was maybe the second game where a specific piece of text haunted me late, after completion. 'What can change the nature of a man?' was the first - if you know what game that's from, you'll like Immortal Defense. - Patrick Dugan, Play This Thing

Immortal Defense is a very well designed game that is easy to control and has a lot of replay value because of the freedom granted to the user. The limited suite of points you have to choose from means you have to (gasp!) think about your placement and how your points will work together to destroy the enemies. - Out of Eight PC Game Reviews

The only comparison I can think of for it is a really hot swinger nymphomaniac who has a very particular fetish (In this case, defending stuff with towers), but anyone’s willing to put up with it because of how hot they are. -

This is a game that will force you stop. It will force you think about the world around you, your very mortality and the price you would pay to become immortal. It will LIE to you on a level that Portal never would have dared to go. And you know what the worst part is? You will KNOW it’s lying to you. You will know it is all a lie but you will not want to believe it. Even as it becomes clearer and clearer – even as the inevitable comes right into your sight and starts to strangle your very mind, you will refuse to believe it. - The Angry Pixel

As the story progresses it's fair to say that the Bavakh might be the least of your worries, but I won't spoil the imaginative storyline - you'll just have to play it to find out. -

Great, great, thank you for the reassurance! All I needed was a little piece of info that everything is alright :) Your position in development is the one that I personally admire, it's no good to rush things when you can take your time and polish everything to perfection. Best of luck in squishing those nasty bugs! Your playerbase eagerly anticipates the Steam release!

hi! sorry for the delays. i've been fixing bugs in the v1.2 version, there are about 5 bugs left that i'm trying to fix, and then i can start playtesting for release. i'm a bit of a perfectionist so i tend to make sure there are absolutely no problems before doing a release, rather than releasing it and fixing it later in a patch (which is probably what normal people would do).

I hope it doesn't sound annoying, but is there any news on the game's progress? I can't wait to see it on Steam, but it's been one and a half month since the last time you mentioned how the things are going. Just a little bit of into would greatly bolster my morale ;)

oh yes, i'm adding achievements to v1.2, and a lot more besides that too. the major changes will be:

* Achievement (medals) system added. Forty achievements, each with a different gameplay bonus.
* French, Spanish, Japanese, Portuguese, and Russian translations added, translated by fans.
* Some shader effects added, and other visual improvements.
* Music and sound volume controls added.
* Level speed settings added: during play, you can switch between half speed, normal speed, 2x speed, or 3x speed.
* Some fan-made custom campaigns are now included.
* Widescreen mode added.
* Large performance improvements.
* Some improvements to the menus and interface.
* The game now has three save slots instead of just one.
* A large number of bug fixes and balance changes.

Nice! I hope the game has achievements as an incentive for people who have already played it.

Wow, you're still going strong; glad to see it! Definitely looking forward to giving the game another spin when 1.2 comes out!

thanks for all the nice comments! short update: the game's next version is currently in testing for bugs, but should be on steam soon (within a month or two).
