I found a Minecraft server called BudderCraft Network and it has a Tower Defense mode that feels like those classic defense games where you stop mobs from reaching the exit.
The Tower Defense mode is the main thing they push and it already has a lot going on. There are 15 different towers and 5 classes so you can try lots of play styles while you fight through 25 waves.
Each map has 5 difficulty choices. Beginner is super chill and expert is meant to be brutal since even the owner has not beaten most maps on that setting.
The upgrade system is grid based and you only get 9 upgrades so you have to pick carefully. Towers have a bunch of upgrades to choose from and you unlock paths as you go. You also get 7 targeting options so you can control what your towers focus on.
Rounds are preset so you can learn them and it is not just random luck. There are 9 3D maps and the terrain can block tower attacks so placement matters. After you win you can keep going in an optional freeplay mode that ramps up.
