What you'll learn

  • Build a complete 3D tower defense strategy game in Unity
  • Create enemy AI with waypoint pathfinding
  • Design modular tower systems with Scriptable Objects
  • Implement shooting, targeting, and combat mechanics
  • Build responsive game UI and menus
  • Add animations, lighting, and visual polish
  • Create sound effects and manage game audio
  • Share your finished Unity game with friends, family, and the world

In this course you’ll learn the fundamentals of game development by building a Tower Defense strategy game called "Monster Siege" from scratch, all while learning the systems that power real games. Instead of relying on prebuilt frameworks, you’ll develop your own enemy movement, tower targeting, shooting mechanics, UI systems, audio management, and gameplay logic step by step.

You’ll start with the Unity basics and quickly move into creating playable levels, building enemies, and designing towers that can track and attack targets dynamically. Along the way, you’ll improve your coding skills with concepts like coroutines, singletons, static variables, and Scriptable Objects to create cleaner, scalable systems.

As your game evolves, you’ll add animations, menus, sound effects, player progression, and visual polish that make the experience feel complete. By the end, you’ll have a fully playable strategy game that you can share with the world and a much deeper understanding of Unity game development workflows so that you can get hired or advance your career as a Game Developer.

Why Learn Unity?

First perhaps we should answer - what is Unity?

Unity is an industry-leading, cross-platform game engine that is commonly used for creating 3D, 2D, AR, and VR games. It's a powerful tool that allows you to easily create and deploy games across a wide range of platforms and devices.

If you've played any video games (if you're here, we assume you have), then we're willing to bet that you've played a video game built using Unity... and now you can learn how they're made and build your own.

Why has Unity become so popular to use?

  1. Unity offers a wide range of features and tools that make the game development process user-friendly
  2. It has built-in physics systems, animation systems, and supports a wide range of third-party assets and tools so that you can build anything your imagination can create
  3. There's a large community of developers who contribute to Unity's development, so it's constantly improving and staying at the leading edge of game development.

These reasons are also a big part of what makes candidiates with Unity skills so in-demand.

What's the bottom line?

This course is not about making you just follow along so that when you are done with the course you don’t know what to do other than watch another tutorial.

Instead, this course will push you and challenge you to go from a beginner to a top 10% Game Developer / Unity Engineer 💪.

And... you have nothing to lose.

You can start learning right now and if this course isn't everything you expected, we'll refund you 100% within 30 days. No hassles and no questions asked.

Who is Zero To Mastery for?

You'll fit right in if:

You're struggling to make progress using free tutorials that aren't giving you the structure or clear path to achieving your goals.
You don't want to learn alone. You want personalized feedback, support, and motivation from instructors and mentors and want to be part of a supportive community of like-minded individuals.
You want to learn by doing. You're excited to embrace the struggle of making mistakes that comes with building fun real-world projects you'll be proud of.
You're sick of outdated & boring tutorials. We pride ourselves on having the most up-to-date (and fun!) courses in the industry so that you're not wasting your time and only learning what matters right now.
You can't afford to spend $8,000+ on over priced bootcamps and colleges. We got you. We'll help you go from zero to hired for less than the cost of a cup of coffee a day.

We're not for you if:

You're just going to watch the lessons and take no action. Our courses are all about getting your hands dirty with exercises and putting what you're learning into action by building fun and impressive real-world projects.
You're not ready to invest in yourself or just looking for the cheapest way to learn. If that's you, no problem, use our free Learn to Code + AI & Get Hired guide.
You don't think fundamentals matter anymore because AI can do everything for you. Understanding the fundamentals and how things really work will always be important.
You think AI is going to replace you and think there's nothing you can do about it. Well... if you keep wasting time not learning AI tools & skills, you're probably right. Or you embrace them, and 2x your productivity (and probably income too!).
