Complete C# Unity 3D Game Development in Unity 6 (Udemy.com)

Build 5 playable 3D games in Unity 6 using C#. Learn real coding skills and master core game dev techniques.

Created by: Rick Davidson

Last updated September 2026

Our take

Based on the ratings of 49,095 students, a sample of their written reviews and the syllabus, as the course stood in September 2026. No course pays to be reviewed.

Five playable 3D games, built one at a time in Unity 6, with C# taught along the way. That is the whole pitch, and the syllabus backs it up: 192 lectures over about 27 hours, split into Obstacle Dodge, Rocket Boost, Galaxy Strike, Royal Run and Sharp Shooter. It's GameDev.tv's sequel to their original Unity course and assumes no coding or Unity experience. About 264,000 students have enrolled, and the content was refreshed in September 2026.

Reviewers love the structure: short videos, a challenge before the solution, and concepts explained from the ground up. Rick Davidson teaches the opening sections and gets almost nothing but praise. The complaints start when Stephen Hubbard takes over for the later, harder games. Several two and four star reviews say he talks and types too fast for a beginner and often does something without saying why. One student says they gave up even at 0.75 speed. One three star review mentions a mouse-spinning habit that makes the videos hard to follow, and another says subtitles sometimes fail to load.

Still, 32,000 of the 49,000 ratings are five stars, and the 4.7 average holds up. Few courses give a first-timer five finished 3D projects in one place. If 2D is more your thing, the Complete C# Unity 2D course sits beside this one in our Unity list. Expect to pause a lot in the second half and keep the Unity docs open. For a paid beginner course in 3D, this is the one we'd point people to.

Best forComplete beginners who want to learn C# by shipping five small 3D games rather than reading about classes first.
Skip it ifYou want 2D, or you need every line explained slowly; the later sections move fast and skip the why.

Pros

  • Challenge-then-solution format: one reviewer was solving problems before the instructor posed them
  • Short, focused lectures (192 over 27 hours) that reviewers say are easy to follow
  • Covers real systems: nav mesh AI, raycasting, object pooling, procedural generation, ProBuilder
  • Rick Davidson's opening sections explain everything from the ground up, per beginner reviews

Cons

  • Second instructor Stephen Hubbard moves fast and often skips the why, a common complaint from beginners
  • One 3-star review flags a distracting mouse-spinning habit; another says subtitles sometimes fail to load
  • Breadth over depth: a 4-star review says it gets your feet wet but is not enough to master
They build the lessons in such a way that you learn while you are building the games which makes the experience awesome and easy to follow.

Marked All Levels but built for true beginners; no C# or Unity needed, just a machine that runs Unity 6.

Unity Awards Best Paid Course

This course has been updated to Unity 6, but is still compatible with older versions of Unity.

This is the long-awaited sequel to the Complete Unity Developer - one of the most popular e-learning courses on the internet! Completely re-worked from scratch with brand-new projects and our latest teaching techniques. You will benefit from the fact we have already taught over 2 million students programming and game development, many shipping commercial games as a result.

Unity is an incredible 3D package used for making video games, architectural and medical imaging and more. The challenge is that it's big and complicated to use, especially for complete beginners to coding and game development. We make learning to code easy and fun by leading you step-by-step through the process of creating exciting games.

Get plugged into our communities of amazing developers on Facebook (nearly 20k), in our own Teaching Assistant-curated Community, and our student Discord chat channel.

If you're reading this you probably already have everything you need to get started. Unity is a free download. With regular access to an internet connection you'll be able to engage in our thriving community. Even if you have no experience with coding, or with 3D packages, we will guide you through everything from first principles. Starting slow, then building on what you learn, you'll soon have a very solid working knowledge of Unity.

You’ll build five fun games, each teaching you key skills in game development. From the basics like variables and collision detection to more advanced stuff like procedural generation and AI, you’ll master it all - while dodging obstacles and blasting aliens!


  • Create an 'Obstacle Dodge' game. Learn player input, collisions, variables, and if statements. It's the perfect way to get your feet wet in Unity.

  • Launch into "Rocket Boost", a physics-based game. Mess around with forces, namespaces, and classes. Push that rocket—and your skills—even further!

  • Gear up for "Galaxy Strike", an old-school rail shooter. Master Unity's terrain and timeline tools while coding arrays, for-loops, and coroutines. Arcade fun with a modern twist!

  • Craft a procedural endless runner in 'Royal Run'. Build worlds that never stop, use lists, pickups, animations, post-processing, and more.

  • Get your eye in on "Sharp Shooter", a first-person shooter. Tackle nav mesh agents, enemy AI, weapon switching, raycasting, and prototyping levels with ProBuilder. Because who doesn't want to make an FPS?


Don't take our word for it, please see the amazing reviews students have taken the time to write. We are proud to be transforming lives, and equipping 1000s of people with valuable new skills. We would love you to become one of them now.

The course is project-based, so you will not just be learning dry programming concepts, but applying them immediately to real indie games as you go. All the project files will be included, as well as additional references and resources - you'll never get stuck. There are "talking heads", powerful diagrams, quality screencasts and more.

For each demo game you build you will follow this process...

  • Be challenged to build the entire game yourself.

  • Be shown step-by step how to build it.

  • Be challenged to apply, and re-apply your knowledge regularly.

100% Above expectations! They build the lessons in such a way that you learn while you are building the games which makes the experience awesome and easy to follow. Furthermore they have split each part in concise small video that contains specific information each which helps a lot!

By Robert on 6/21/2026

It's an excellent course, and you will learn a ton. By the end of the course I was pausing and adding functionality, solving many of the problems before Steven even had chance to pose them as challenges. This is a testament to the course quality, proving that it was teaching me to independently solve problems rather than just like-for-like configuring unity objects. The review loses half a start because I wasn't a fan of the on-rails shooter, but I guess it was an opportunity to learn a few useful things.

By Jesse van Brienen on 6/20/2026

A well made course. It starts simple with explaining of how to navigate the interface and such, and early on you will getting to learn to program as well. I still have a hard time to remember all the new programming terminologies and what you need to type to get it working, so making notes is a very good idea to get all of that into the and it help to look back if you forgot something. And practice of course! :)

By Avishek Gupta on 5/31/2026

After going through most of the course I have to say this is probably the best unity course available. Both the instructors are very knowledgeable. I have learnt a lot here and thinking of starting game development as a solo developer. Maybe the next step would be to learn a bit of Blender.

By Nathan Fogliata on 5/26/2026

Pretty good, love the small episodes and the way it demonstrates everything you need to get going in Unity. Only complaint is that sometimes i'd like things to have more explanation by the instructor himself. It's good to have left the unity documentation in the resources tab but it'd be better to have him explain it directly on a deeper level

By Roy Charles Sorvari on 4/10/2026

Pretty good course, here's what i thought of: what i liked: -The games were good, I'd recommend this course to other students. -How the difficulty of making each game, like the first 2 games were simple and beginner friendly, and galaxy strike was intermeditate, and so on. What could be better: -this course should have 1 or 2 different solutions in case a student makes a mistake,, for example, on lecture 78 I couldn't make my ship move even with the exact code. -the lectures should be a bit slower so student can have an easier job following along. :)

By Conrad Neumann on 4/3/2026

I looked at a lot of different courses for an entry into Unity and this is by far the best one. The course is densely packed with loads of different useful concepts and is worth every single minute of it. Thank you very much for this! On a side note: I really like Stephens speed, because normally I tend to speed up course videos. However, Stephen is sometimes thinking two or three steps ahead and then misses to exactly explain the steps he is taking (this is happening mostly when adjusting things in the Inspector). This can get confusing, and I found myself sometimes rewinding videos to understand, which option in which subset he is actually referring to. Still, it is absolutely no reason to reduce the course rating, because Stephens lectures are absolutely great regarding the content!

By Melih Can on 2/19/2026

So far the course is good, I am on the last game section. I started from 0 and I learned a lot. However, Stephen's pace is sometimes too quick. I saw some comments related to that before I get the course and after taken the course some students also mentioned it on the lectures. I also saw the Stephen's response, nice to see you are reviewing the comments. I understand that it is kind a normal since he has lectures on more complex games. Just wanted to remind you this from student perspective. Thanks.

By Muzammil Abubakar on 1/22/2026

At first I was just amazed by the quality and the teaching style within this course. After a while i was even more amazed by seeing just how engaging it was. Considering how lazy i am naturally I didnt get overwhelmed at all and felt good at all times knowing that I am learning the most fundamental and necessary skills of unity game development at a comfortable pace.

By Scott Moses on 12/26/2025

Another excellent course from GameDevTv. The level of instruction, fun/interesting games/exercises with quality editorial oversight is unmatched by other publishers. I've since purchased the GameDevTv Lifetime membership (when on sale), but still use the Udemy versions I've purchased. I took the original version of this course about 5 years ago, and went back through again this time, to use each game as a basis to create my own game design versions. Even with time constraints, I could use each lesson as a daily exercise (create it myself as a challenge, and then watch the instructor's version). Then, git branch and replace the characters, scenes, graphics, and expand the game play/logic.... Thanks Rick, Stephen et al for re-playable and consistently updated content.
