When you thought that you would no longer see games with original mechanics... we are proud to announce that we have created the first PHYSICAL tower defense game! Will it be a new genre? :)
In this innovative concept, the mechanics of the best tower defense games are mixed with the dynamics of classic physics-based games, which in addition to giving the game a unique depth, also makes it unpredictable and fun!

In no other game of this type does the background play as important a role as it does here, as the impact of gravity and physical force on the behavior of enemies and your defenses will be crucial. You will be surprised to at times to be hallucinating with the advance of the enemies and forgetting that you must stop them!
Both fans of strategy and those seeking action will be assured to have fun because it is not enough to place your towers and get comfortable, your intervention must be constant!

In SOS defense you will have:
- Physics and gravity acting on the invading enemy, but also on your towers and powers!
- 3 game modes, for a total of 45 levels and more to come!
- Challenges that you can only overcome when your skills and strategy are at their maximum.
- Endless modes, in which your defenses must stop avalanches of enemies.
- 2 Special levels, which will force you to change your game and will put you to the test.
- 6 types of unique towers and improvements to customize your strategy.
- More than 20 enemies with different characteristics, including bosses that will make it very difficult for you.
- Powerful special powers, under your control.
- With 45 achievements and a leaderboard to see who is the best, you will stay motivated.
- Become an expert, using the encyclopedia with information about enemies, towers and special powers.
- You get the full game, without ads, without in-app purchases or paywalls :)
- A unique aesthetic... put on your headphones and immerse yourself in the SOS defense world!

We've worked with a lot of passion to create an original game, but also one that is fun and engaging!
Thanks to your support, we will be able to continue advancing, since we have many ideas planned for future updates.
Have fun! :)

Almost excellent


I like the idea, and I might be missing something, but I’m stuck using the same 3 towers, no upgrades and one wall like special power. It says I’ve unlocked a new tower and power, but I haven’t seen them or been able to use them. Maybe I’m too early in the game? It’s like. Pachinko setup....balls come from the top and you set up spinnng “towers” to kill or put an effect on them. They reach the bottom, lives are taken away till you die.

I’m just not seeing variety quick enough....and the $ production is super slow, so you just have to sit there....well when a tower gets “old” you can sell it before it explodes, but that’s the only other $.

I’m sure I’m either not getting something, or are impatient, but after 5 levels and I cant level up towers or choose different’s getting old quick. If it becomes more clear and variety shows up, it may be a 5 star.

Hi, thanks for your comments. We have just done an update to improve the user experience in the firsts levels... if you have reached level 5, you are one step away from level 6 which is a special level and this one proposes a different gameplay and in the next levels more towers, upgrades and power ups will be appearing! ... if you can, give it a new opportunity. We want the game to improve, we appreciate your comments :)

Still too difficult.


Maybe I’m just bad at this game, but even after the balance update, I still can’t beat level 2.

Hi, thanks for your comments, you are right :)
I just upload a new updated (1.1.0), in this I made a general rebalance of the whole game, to adapt it to the request of the users!
We have tested it and 95% of users can now pass it ... if you can play it again, try it, you will feel much better :)
I hope you enjoy it and I will be attentive to your comments! Thanks

Really Dull, Real Fast

The Supreme Yoda

This game gets really dull, really fast. I can only watch balls roll down and spinning things kill them for so long... I have played a lot of tower defense games and appreciate that the developer tried to create something original, but this game just gets tedious and boring. I thought it was clever at first, but the repetition kills it.

Hi, thanks for your comments!
You're right, the game was difficult, plus you had few resources to buy towers. We just did a new update (1.1.0), we made a general rebalancing of the whole game, to adapt it to the request of the users. If it is possible to play it again, you will see that it is more fun and as you advance in the levels you will find new elements, new towers and new power ups, that will hook you with the game. We will be attentive to your comments to continue improving!
