Fired up MCC this morning to get a few games in before work. Selected exactly what I wanted to play, with the exact team size and within 30 seconds I was playing king of the hill 8v8. Finished the game and finished two very generic challenges without even trying (kill 25 players and finish 1 match). Gave me 500Kxp towards my account rank and unlocked 2 nameplates for the 20th anniversary celebration. Was a very enjoyable 30mins while I had my coffee.
No oddball or CTF that I dont enjoy. Just some nice slayer focused game modes that I got to choose supported by some challenges you finish just by playing naturally.
