Can I use UNET for co-op game? There is a limit by number of players: 20. If my game will download 100 people… Maybe must I use Low Level API and Headless Server?
UNET itself doesn’t set player limits or restrictions on game types. Practical limitations will come from how much data you’re actually syncing between players in your game.
No It has. Please, scroll down: Game Development Software: Build a Multiplayer Game | Unity
Unity Personal: 20 Concurrent players
Unity Plus: 50 Concurrent players
Unity Pro: 200 Concurrent players
But I do not understand is it for simultaneous presence on one scene? Is there no restriction for Low Level API?
