You'll need cheat engine - cheatengine.org
TL;DR version
just hit create server and do a basic 4byte memory scan for the max limit, change the limit slider and rescan for the next value.
repeat this until you have only 2-4 results.
change them all to your desired limit and start the server.
keep in mind only 16 or so player will actually be able to join before other new players just get black screened and kicked.
also keep in mind even if you're on easy mode, all players that are alive will need to be in any elevators to continue to the next level unless they all leave and rejoin once the host has continued past the level.
enjoy!
