Among Us

So make a lobby by yourself then make it 15 people and wait till about 10 or so (flip private and public on and off if no one has joined in a bit) then switch to private before you start and set yourself as the impostor. Rinse and repeat, depending on the people in your lobby you may have to make a few more. Do this for this and the 200 kills then welcome your gamerscore. Hope this helps! Also if you got another phone/other device then add them to your game for free kills!
