I'm new to modding and wanted to know if theres a guide for making a proper lms map (team and solo).  I was inspired by one of the workshop maps and wanted to make my own custom map. So far I only have the mystery box, power and gates working. I want to make a trigger for the power, when actived the round starts and it is constantly increases rounds. If theres a video, wiki, post or even scripts on creating a proper map please reply or dm me (on the forums or discord).

Basically this is what I need help with (video, wiki, post or even scripts will be helpful)
1. Disable players from reviving other player or respawning in game and declare the last player standing the winner.
2. Custom power triggers (spawn zombies when active and play a sound effect (globally and specific areas)
3. Creating different shapes on map (Like a right triangle, parallelogram on grid, but actually have a 3d shape ingame)
4. Allow zones to switch to deadzones when the power is activated.

The map itself:
