The Game's failed to get Eminem on a Verzuz battle ... so now he's trying to bait Slim Shady into responding with a diss track.
Game released his long-delayed "DRILLMATIC: Heart vs. Mind" album with 31 tracks ... but the song everyone is talking about on social media is the 10-minute Eminem diss song "The Black Slim Shady."
The Hit-Boy-produced track mostly comes off slapstick with the West Coast rapper using silly voices ... akin to Eminem's classic "Stan" track but Game does pepper the song with several personal attacks.
Disrespectful topics range Em's past pill-popping addictions, his songs only get played within white America and how Game believes Big Sean and 6ix9ine are better rappers.
50 Cent-- who also has been ignoring Game's Verzuz challenges -- also catches a few strays on the track ... mainly for his lack of rapping output these days.
Waiting for your permission to load the Instagram Media.
Of course, Em is one of the biggest artists of all time -- actually the 2nd highest-selling -- behind Garth Brooks, but Game says his beef is for the spirit of hip hop culture ... which just celebrated its 49th birthday yesterday!
