What is your best Xbox gaming experience?

I was playing Battlefield 3 Karkand stage GrinReaper01 (clan member) and I was on the same team. I spawn right next to him while he was sniping. As soon as I spawned I look down and saw a tank looking up at us while we was on the rooftop of a building.
My clan member said in a raised voice "MOVE MOVE MOVE MOVE". We both start sprinting to the other side of the building. We didn't make to the other side of the building but we did mange to survive the blast. What really caught our attention was my partner
fell from the rooftop to last room in the building and i fell from the rooftop to the second to last room with only 3% health.

the absolute best experience I ever had gaming, was when I was playing halo 2 a few years ago, 3 of my team quit and I was up against 4 other players in slayer on colossus map. I basically crouched and hunted the other team down, made it impossible for them
to find me quickly and win.

2nd best was playing a CTF on halo reach and half of my 8 member team quit on a CTF match.... 4 of us just stuck around and made it impossible for the other team to win. we totally skunked them for the 12 minutes left in the game. we didn't win...but the
other team never even touched our flag either

Going to my neighbor house/friend house and invite other to play all night rock band games. i really miss those times.

Complete Halo 3 LASO with my cousin. Unforgettable moment :').

It's not really my style of game so one of them is the first ever chicken dinner I got in PUBG.
