“Immortal Defense is a tower defense game for people who abhor tower defense games. Or people who like them. Or people who think they're okay.”
Anthony Burch, Destructoid

“Immortal Defense takes a simple, oversaturated genre and elevates it to another level entirely. The existentialist storyline is not only compelling and thoughtful, but it's probably the best explanation for "turret defense" gameplay I've seen yet.”
9 – Derek Yu, Game Tunnel

“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.”
10 – Greg Costikyan, Game Tunnel

About This Game

Immortal Defense has been widely praised for the game's storytelling and unique twist on the tower defense genre, many consider it a cult classic of the subgenre. Its story was written by novelist Jeanne Thornton, and its universe is based on the novel Raberata by Robert Bisno. This new Steam release features many improvements over the original release: Steam achievements which grant gameplay bonuses, leaderboards, improved graphics and performance, widescreen support, an improved level editor, and much more.

WARNING: This game involves a lot of flashing lights and visual effects. If you have sensory issues, such as epilepsy, this game might cause more problems for you than other games. There is a way to turn the visual options down, but even with all the options turned down, it can still be quite flashy.

Immortal Defense has a story-driven campaign with 100 core levels and 50 optional side-quest levels (which can be completed for bonuses that help you with the core levels). The game takes about 20 hours to complete everything in. The game comes with the soundtrack, which is by Long Dao and classical composer Walter Eres. There are also Steam Cards which were hand-painted in watercolor just for this Steam release.

There are 26 types of enemies, each with its own abilities and unique interactions with one another, and 11 types of towers, each of which goes through different forms as they are upgraded, and each of which gains new abilities as the player collects achievements. These are not standard enemy types like "flying" or standard tower types like "long range and slow"--you haven't seen these before in other tower defense games. The game also comes with a level editor, with Steam Workshop support, and is pre-packaged with an extra 62 levels created by fans.

Incredible abstract tower defense. It is extremely good. Probably even the best tower defense available in the platform.

Surprisingly good story line too!

It doesn't look like much, with graphics that would be more at home in a game made on the turn of the millenium, but I struggle to imagine how the bizarre setting of pathspace the game is set in could be presented another way.

This game is Tower Defence at its WEIRDEST. And this always sounds corny on reviews I read but boy is it story driven. Like, basically as advertised.

Great game to drop in and out of, the game boots quickly and each individual stage is less than 10 minutes (barring the tiny handful of 'endless' stages) and no sound-only cues, so you can play it on the fly between stuff.

A genuinely novel take on tower defense, and with an affecting story as well. I bought it long ago, before it was on Steam, and was only too happy to buy it again now that it's here and has a few more bits of polish added. I'm pleased to see that what I thought was an obscure little game that only a few folks knew about has actually gotten a great deal of well-earned recognition.

I bought this game 3 times (before it was on steam, then: "ah were is it already? Nevermind, I'll buy it again").

This game is fantastic, and I am not sure I can exactly pinpoiny why.
Of course I love a good and not too punishing tower defense game. But I did not expect to find such a good story there, with a great lore and an economic and mastered narration. I seldom had games that generated that much emotions, stuff I normally find in books. Except it is a game! And a good one too.

I purchased the original version of Immortal Defense quite a long time ago, and I'm glad that it has finally made its way to Steam. ID is one of the best Tower Defense style games I have ever played.

On a mechanical level, the towers are not the formulaic set you find in most other games. You know, the "weak but fast" tower, the "long range and slow" tower, the "splash damage" tower, etc. You won't find that here. Each of the towers has vastly different behaviors, making you think more carefully about placement. Behavior can change as you upgrade them, and they can also interact with your cursor as well (which is a weapon in its own right).

The game is also very challenging - experienced Tower Defense players will be tested here. But, the difficulty can be adjusted along the way, so if it's just too hard, you can dial the difficulty down a bit - for the one level you're having trouble with - and come back to it later if you want.

Visually, Immortal Defense is fun. This is an older game but it still looks great. It's somewhere between a dream, a laser light show, and an LSD experience all rolled up into one. The visuals can also be dialed up and down as needed, though, so if it is too much for you, you can get back to a more "sane" experience. I recommend keeping on the higher side.

The music is great too - it has a delicate, mystical quality that fits very well with the art style.

Generally, tower defense games have at most a token storyline, something that is easy to throw away and ignore. But Immortal Defense delivers here, too - taken as a whole, the story of Immortal Defense gets into some interesting philisophical questions about immortality, good and evil, what is really important, etc. The towers (called Points in the game) come out of the story, and their names and functionality are drawn out of it as well.

It might be a bit too cerebral for a lot of people, but it won't interfere with the gameplay.

For the Steam version of the game, there are new challenges that you can complete for additional bonuses during gameplay. There is also a leaderboard.

Overall, I rate this as a very strong buy for anyone who enjoys the Tower Defense genre and is looking for something a little different. Visuals aside, I put ID on the same level as other TD greats.

Disclosure: Studio Eres provided me with an advance copy of the Steam version for the purposes of play testing and review.

"Wa-a-a-it a minute, is this another one of those tower defense games? How many of them do we really need?" - you're probably asking yourself at the moment. Why yes, indeed, it IS a tower defense for PC - a platform already chock-full of various games of the kind. You might have already played Defense Grid, spent some evenings grinding Defender's Quest, maybe partied in the co-op mode of Dungeon Defenders with a couple of friends... So, why waste time on yet another game of an exhausted genre?

To put it shortly - yes, we do need Immortal Defense. Right off the bat - when playing ID, you're not just an omnipresent authority figure (c), you ARE the guy who actually shoots stuff in top-down perspective. That little mouse cursor on screen that lets you build your towers? That's you right there, or rather your soul, personification of your willpower - whichever you prefer. It's the embodiment of a player in the game, and one of the signs of its unorthodox approach - combining the control mechanics with the actual gameplay, making the player a major part of the action while removing any unnecessary medium. Very few games do this ("Brothers: A Tale of Two Sons" comes to mind, check it out when you can), and to see this from a "mere" tower defense? Not bad, not bad at all.

But then we move beyond the interface and controls and look at the game itself, and... Geez, is that a plot segment I see in-between the missions? Some kind of a mystic space opera? Why do I even need a plot in a tower defense game? It boils down to shooting unremarkable enemies throughout a hundred of levels anyway, right? Right?... Well, not in this case, it doesn't. From the very beginning the game makes you feel responsible - you are not just a figure behind a computer desk, consolidating some defense force around your planet. You have been chosen to leave everything you knew behind and transcend into a new form of being - the form no one really knows much about. It's the sacrifice you made for your loved ones - and each message from them, received after successful battles, reassures you in the righteousness of your task. To become a god of space between worlds, to be the last hope of your home planet - what's not to like?

And yet, the Universe operates on a different level, and not every action has clear consequences. Concentrating your will to create needle-sharp "points" - your line of defense against the invading armies - you fail to notice how decades after decades run by. The Universe is engulfed by war, and there's little time for you to think of what the future holds for you when you finally turn homewards. But when you do... will there really be home to return to?

There are many other beings like you, created with the same mission in mind - to protect, to defend, to repel. And yet, as you soon realize, not everyone can bear the centuries of loneliness. For that matter, can you?..

But the transcended existence has its own benefits - with each passing day, your memories shatter, but your will gets stronger. Learning more and more advanced techniques, assembling more and more powerful points, you manage to overcome the limitations of spirit once imposed upon you. What lies beyond? Will it be paradise for those who rely on you... or will you only descend deeper into hell?

To put it shortly, Immortal Defense is not an easy game to review. The controls and mechanis are closely intertwined with gameplay, and the gameplay itself depends heavily on the story. There are no decisions per se, no roads to take, but the final result still doesn't disappoint - in the very end it feels like you walked your own path, made your own choices. Complicated relationships with your family's descendants and the ones who you once thought your enemies only make it harder to progress, and the game itself becomes more and more complex with each mission, never forgetting to introduce yet another enemy pattern or some dimensional trick to keep you off guard. Overcoming those and using every available ability to your advantage - that is the measure of a true Ghost of the Path. And trust me, with the Steam release, the game has obtained a LOT of new shiny toys for you to experiment with, as well as a real sense of an almost RPG-like progression - just take a look at all the bonuses that achievements and medals provide!

I first played ID when it was released years ago, and I still play it to this very day. With each playthrough, I feel as if I learnt something new - not just about the game, but about myself, too. Is there anything else to wish for? Well, maybe some cool graphics effects and nifty tower designs - in which case you'll find those here aplenty. ;) Happy hunting, Great Ghost! And never forget where you came from.

This is an absolutely fantastic little tower defence game.
It's mechanically sound and the tower interactions (and limitations) lend themselves to requiring interesting strategies on most of the later levels. It's never a case of "the slow tower + the aoe tower" always assures victory.
Let's be honest though there are hundreds of tower defence games out there so what sets this on apart?
The story.
The story is a fantastic exploration into what it means to be immortal and explores such themes as loneliness, betrayal and insanity. It's astoundingly deep content to have in a game of this genre.
It's hard to say any more without spoiling the experience so just go play it yourselves!

Immortal Defense is a pretty interesting tower defense game. It touches on some odd topics for a video game but it sure made me think about things that very few games can manage.
The story itself is pretty enjoyable and the game takes awhile to run through. So it is a decent investment on time I found. With six different plot lines that take place over sixteen missions a piece. And a bit of extra content if you can find it. It certainly kept me occupied for awhile.
It follows the adventures of an almost unnamed protagonist as he becomes his worlds only defense against an alien menace in what they call "Path Space" Which feels a lot like hyperspace, to me. And that's what it plays as, it is a short cut from point A to point B in space. And you are there, looking down at the ships trying to venture through. And this gives you a severe advantage over them. But in this state you are incorporeal, and seperate from your body. Time passes differently. How do you handle this, all the presure of so many lives depending on your constant vigiliance and being seperated from everyone you know and love. The story touches on this in many ways. And also friendship and betrayal as well. But I'll leave those for you to discover.
It's also quite atmospheric and charming. I haven't seen any tower defense games where your towers talk to you and have their own personalities. It's very interesting to see what all they have to say as you play the game. And how they respond to the things happening o nthe screen.

One of the things I like most about Immortal Defense though is the music, it really draws me in and makes me feel there, in the moment and I think grabbing the soundtrack is worth the price of admission by itself. But that's just me.
Music aside, the visuals are another strong trait the game has, falling somewhere between a rave and some sort of bizzare drug trip, they are certainly something to see. Though on higher settings might be a bit much for some people of more frail constitution. But that is easily adjusted on the main screen via slider.

Anyway, This is a game that I absolutely adore and have played through multiple times. Twice for fun and once to get to the secret stuff! Worth the money I spent, way back before it got on steam. And I will be buying it again now, for friends to enjoy!
Overall, I would say, if you like tower defense games, or games that touch on philisophical things, this would be a very strong buy. The musics and graphics are great, for the games age, and it is really more about the aesthetic amyway, at least that's how I feel!

At this point, I'm likely to ignore something that's described as "a tower defense game." There are a lot of them out there, and many don't ultimately have much to offer. But Immortal Defense is an exception, and I'll likely use this new version as an excuse to play through the game again.

Immortal Defense has a unique style, engaging mechanics, and an evocative story. You might not expect the writing to be a strength in a game of this type, but that's one of the elements that set Immortal Defense apart.

I'm also looking forward to Studio Eres's other upcoming release Saturated Dreamers.

Whether you're new or old to tower defense games, Immortal Defense is a good buy. With tons of unique mechanics but still holding together what makes a good tower defense a good tower defense, and on top of that all a great story considering it's a game where you're shooting geometrical shapes flying on a line... Immortal Defense is amazing for what it is.

In Immortal Defense, you play as a Pathspace Defender whose goal is to defend your home planet by literally becoming a god and shooting invisible hellbeams from another plane of existence at people who are invading you. You do this by what else- placing towers! While the story and gameplay get more complicated than that (and bring all sorts of delightful twists and turns), that is the basic premise to the game.

If you're new to the game, you might be pleasantly surprised by the gameplay and strange quirks it has. Each tower is more unique than the usual tower defense tower, with every single one having completely original properties and not just "the splash damage tower" and "the one that shoots fast". Not only that, but you have a stake in the action as well; you use your mouse cursor to charge up attacks and interact with some of the attacks of your nearby towers to efficiently take out harder enemies. The strategic depth of the game gets pretty crazy later on, with enemies you have to pinpoint and "snipe" with your cursor or else they'll buff other enemies to the point of being unstoppable. You'll also find that although the story starts out a bit slow it picks up very fast and perfectly placed cliffhangers keep making you want to play more.

If you're a returning player, why buy the steam version? The non-steam version is currently pay what you want on the site (unless it's been taken down). The steam version has all kinds of great new features, from almost doubling the length of the base game with side missions and campaigns to giving you permanent "upgrades" sort of by completing weird challenges to make the notoriously harder levels a tiny bit easier. Not only that but there is a more in depth graphical system (with widescreen support finally) and leaderboards/steam workshop integration so you can play other people's levels that they made with great ease.

So would I recommend Immortal Defense? With an overwhelming response, yes. It is one of, if not the best and most unique tower defense game I have ever played and the story is also seriously great (even though it can come off as trying too hard a time or two). For 9-10 dollars this game absolutely deserves to be checked out.
