I'm finally done with my new video: "Common Stealth Level Design Mistakes".
Essentially, it is a long collection of mistakes I've witnessed (and done myself) in terms of level design stealth setups. Trust me, I've seen a lot after working for +14 years on games with a more or less strong stealth focus such as FarCry 1, Crysis, Crysis Warhead, FarCry Primal, FarCry 5 and especially Splinter Cell Blacklist. Of course, I won't just list the bad things but also offer solutions and hopefully animated it entertaining enough.
Enjoy
