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. -

thanks! but FYI, you can email me rather than re-buying it to get a new download link, you don't need to re-purchase it each time (the game's website mentions that somewhere, along with my email). part of the reason it'd be good to have it on steam is to avoid the expiring download link problem of fastspring/BMT-micro.

I admit it's really sad that this is still in Greenlight. It is one of the better tower defense games I've ever played. I've even purchased it 4 times in all, due to lost copies or the like (This is a claim to how good it is, not a complaint :P. I totally didn't mind throwing money at this each and every time.)

I definitely agree with it not being mobile, mobile and touch interfaces really stink. Griming up the screen and obscuring view of the playfield for very little if any actual advantage.

Here's hoping that the impending death of Greenlight will prevent games like this from being locked up in limbo.

(i do think it's much more faster-paced than most tower defense games, because you yourself take part in the shooting and use special charge attacks and so on, in contrast to games like defense grid where all you do is place towers.)
RPGCreations  [author] Apr 4 @ 11:29am 
the game would not really work on mobile or tablet, mainly because it's so focused on the *mouse* as the means of control. a touch interface would entirely change the game and make it unrecognizable, because the whole point of the game is that you are a mouse cursor that shoots. there is no equivalent mechanism for touch screen controls; how would it even work, would it only shoot when your finger is on the screen?

secondly, the game is very fast-paced later on, perhaps you only played the first few levels and judged the speed on that? they are just intro/tutorial stuff so they're necessarily less hectic than what's to come (check out bormac's let's play videos for the later levels to see what i mean).

You should consider trying to port to android or ios, I think you would have much better luck, but the game is definitely unique, but its a little slow for my pace. Why i think a touchscreen on a mobile device would appeal to much larger audience.

Been playing the demo for ages, keep coming back to it. Finally bought the game today and i'm kinda shocked that this is STILL on greenlight. How can this not be up on Steam properly yet?

It's a real shame that this hasn't been Greenlit yet. I finally got around to playing it, and it's amazing. Now to try to unlock the secret levels...

I played this a while ago when it came out. The fact that it's still lingering in Greenlight hell is a crime.
