The Queen's health and death syncs between clients, player deaths sync, metroids disappear if they are in the same room as another player when the metroid dies, array syncing is vastly improved and should be 100% accurate, and half of the rooms leading up to the queen will unlock the doors if another player kills the last metroid while all players are in the same room.
Revised because attempting enforcement on hyper-specific use cases is, quite frankly, dumb, and places unnecessary burden on project management. Unless a specific issue arises, this is the final license for the project.
Good riddance, 2020.
