this launcher has a tab for minecraft news, but that tab really justs embeds part of the minecraft website. so, by looking around and clicking on links, it’s possible to go to other pages!

i don’t remember exactly what i did there, but iirc it involved going through some microsoft help page and from there going on bing. and once you’ve got access to a search engine, you can basically do whatever. here, i just searched “play doom online” or something and ended up on that website!
