I personally was playing TD games all my childhood and played through almost every single one. However, when I tried other tower defence games on the market I found that they were way too simple, or just plain boring. Some of what I found were not even tower defense offline games. Selection of towers was too small, they was either easy to build or did not hold enough without donations. Enemies managed to tower rush you in case you play td games free. No matter which tower you got, your tower defence would crush and burn and your castle would fall. So I thought: there should be td games free to play with different options for towers and defences and all the perks of great strategy games. I made this tower defense offline game in hopes that it will give you the depth of old school td game experience on modern devices. Strategy is important here because the resources available to achieve these goals are limited. Strategy here involves setting goals, determining actions to achieve the goals, and mobilizing resources to execute the actions. A strategy describes how the ends (goals) will be achieved by the means (resources). It is a common knowledge that strategy typically involves two major processes: formulation and implementation. Formulation involves analyzing the environment or situation, making a diagnosis, and developing guiding policies. It includes such activities as strategic planning and strategic thinking. Implementation refers to the action plans taken to achieve the goals established by the guiding policy. In this game to succeed you will need to understand both of these processes. Hope you like it. And if you don’t: leave me a comment so I can make it better. =) We have got everything that makes great playing experience: tower, best strategy offline elements, sci fi setting. Explore one of the best tower defence offline games out there and unleash the power of the best tower you can build. https://www.facebook.com/Module-TD-Sci-Fi-Tower-Defense-2151672478181003/ http://moduletd.com/ ## Key features - Offline Tower Defense - Highly Customizable Towers - Modular Elements - Elemental Bonuses - 80+ Levels - Strategic Gameplay - Achievements ## Pricing and in-app purchases Base price: Free. **One-time purchases** | Purchase | Price | Type | | --- | --- | --- | | Metamaterials and Matrix | $49.99 | one-time | | Matrix Good-Sized Pack | $8.99 | one-time | | Matrix Average Pack | $4.99 | one-time | | Matrix Large Pack | $17.99 | one-time | | Matrix Moderate Pack | $1.99 | one-time | | Metamaterials Average Pack | $4.99 | one-time | | Matrix Small Pack | $0.99 | one-time | | Metamaterials Large Pack | $17.99 | one-time | | Metamaterials+Matrix Medium | $8.99 | one-time | | Metamaterials+Matrix Small | $0.99 | one-time | | Average Pack | $2.99 | one-time | | Metamaterials Huge Pack | $43.99 | one-time | ## What do users think of Module TD Tower Defense Sci?

Only to find that all my tower progress has been completely reset to basic towers. Seem to have lost most of my modules too. Considering others have the same concern for at least a year now, I doubt we are getting a fix for this. Will have to delete. ### 1/5 — Devs not fixing issues and not replying *2026-02-09, version 217* Great game. After months of play all towers revert to the most basic weakest tower. Devs won’t reply or fix. I sent them screenshot evidence. Still ignored. ### 5/5 — 5star *2026-01-09, version 217* Needs more levels ### 5/5 — Amazing game *2025-11-24, version 217* It’s challenging and fun I hope for more updates sometime my game shows the same tower instead of multiple and also it resets my stats completely sometimes and I have to fully start over but other than that it’s great I hope that gets fixed! ### 4/5 — One issue *2025-11-13, version 217* My favorite tower defense game ever. Only issue is it glitches from time to time and I can’t select my towers to continue playing the game. I have to delete the game then reinstall losing progress ### 1/5 — Had this game for years *2025-11-11, version 217* Assumed it was dead, but it’s still fun. Was thrilled that the devs updated the game… but they broke it. Twice now. I’ve restarted the game ( from lvl 1) a few times, and restarted again after their first update in years because they broke all the turrets. Now, you can’t even select turrets. Please devs… fix the game. EDIT: The dev disappeared for a year. Almost as soon as they came back, I redownloaded it. But, NOW FOR A THIRD TIME ITS BROKEN. WHY?!! ### 1/5 — Broke *2025-11-11, version 217* Why did you just break your game? Only 1 tower. They don’t fire. ### 1/5 — Decent idea *2025-11-09, version 217* The app is buggy. For example, pausing it doesn’t guarantee you would continue if the app restarts. Plus, after the most recent update, only one type of gun is available, so no matter how much effort you’ve spent on upgrading something, you are out of luck and now have to use the gun they give you.
