Today I want to talk about a research to find and play an old game I played on mobile phones. Unfortunately it wasn't available or playable anymore and I looked into alternatives. This post is just a little history of my research, that's all. The conclusion is: Unfortunately I don't use iPhone or an Android with Google Play Store anymore, so cannot play these anymore.
2009 there was this game geoDefense Swarm, which I loved very much. Played it
a lot on my iPod Touch (i think fourth gen?).
https://www.mobygames.com/game/46398/geodefense-swarm/ The iPhone version
of geoDefense Swarm appears in the book 1001 Video Games You Must Play Before
You Die. Later when I got an iPhone 5, the game was no longer playable on this
device. It was just too old and not compatible. This annoyed me a lot.
Years later after switching to Android, I noticed the game geoDefense Swarm
was only available on Apple devices. This annoyed me a lot.
2011 or a bit later I found out about an free game, that is inspired and
very, very similar to that game: ZDefense HD. Loved that game and it was
similar in look, game design and feel as geoDefense. This didn't annoy me.
6 years ago, 2020, I did a recommendation to the game on Reddit
https://www.reddit.com/r/truegaming/comments/gwbh2m/comment/fsu29th/:
My favorite Tower Defense game is an old one, which is a free and open grid,
without lanes. But it is exclusive to Apple Store and does not work on newer
phones anymore. Luckily there is a new game inspired by it (you can clearly
tell) and its really good too. To be honest, this is the only tower defense
game I like and one of the few games I actually played on my phone.
ZDefense HD
Today in 2026 I looked at the link again and the game does not exist anymore.
Maybe because its no longer compatible, who knows. This annoyed me a lot.
So I begun to research again and found this blog
https://zdefense.blogspot.com/ from the developer of that game. ZDefense is
also available on https://www.amazon.com/ZStudio-ZDefense/dp/B0058OUJA4 and
the free variant https://www.amazon.com/ZStudio-ZDefense-Lite/dp/B0058OVI9A
with Minimum Operating System: Android 2.1, so don't know how compatible
this is with modern Android. Game is also not available on any other place.
This annoyed me a lot.
I found out that the original GeoDefense was rebuild from scratch by original
developers (if I'm correct) to be compatible with modern devices at
https://www.geodefence.com/ . Bottom of the page has date 2021, so maybe
outdated. The link to the AppStore works, but not the one to Google Play Store. This annoyed me a lot.
At this point, I'm so done. I would be happy if someone does a knockoff of
geoDefense, that looks, feels and plays similar. All other Tower Defense games
are so different. And to my surprise, there is HexDefense for Android
https://play.google.com/store/apps/details?id=com.gotow.hexdefense . This looks
amazing and comments are from 2026. But... I am no longer on stock Android and
do not use the Play Store. And game is not available on F-Droid or elsewhere.
This annoyed me a little bit.
My current research led to Infinitode 2 - Tower Defense at
https://play.google.com/store/apps/details?id=com.prineside.tdi2 . A bit different, so not a true replacement for geoDefense or ZDefense. But it looks
interesting, has even bosses! The game is even available for free on Steam
https://store.steampowered.com/app/937310/Infinitode_2__Infinite_Tower_Defense.
This didn't annoy me.
What is my conclusion? Well I'm not satisfied. This is why game preservation is
important. I can find some APK files to install on the net, but I do not trust
them much. Too sketchy to me to install from untrusted sources. Maybe if I get a modern Android phone again,
or even an iPhone, just to game on the go, I'll try again.
