giandeli Hey there!
The "2020" tools are in a sort of beta that's not open to public currently, but will be eventually. Essentially, they kinda "fixed" everything "wrong" with the game, making it a sort of hybrid between WaW zombies and bo1 in terms of mechanics. Anywho, they'll be released eventually, so just keep an eye out for em. In the mean time, if you're looking for help making a map that isn't a 7 year old video on youtube, lemme know!
