Anne, I haven’t personally finished that series but I’ve watched a few of the videos and it looks fantastic! The primary difference is that mine is a first person shooter, while the Unity shooter series has a top down view. My series is also much more comprehensive (50+ videos vs 12) but that doesn’t necessarily make mine better (just longer). If you are looking for other series I also HIGHLY recommend the FPS series by Mike Geig called Merry Fragmas. Mike is the best.
In preparation for the tower defense series I’ve been creating some low poly tower defense models. In this episode I show a workaround for getting our assets from Blender to Unity without annoying rotation issues.
