Just finished playing on game on the new Battlefield 1 DLC that took over 81 minutes (1 hour 21 minutes) to complete.
The mode was Frontlines and the map was Fort de Vaux. This map is basically the new Locker/Metro map with some exterior access.
It was a fun match that kept swinging back and forth for map control, but in the end my team ended up winning the match.
Nice! This game mode certainly lends itself to prolonged battle if the teams are evenly matched.
Funnily enough though, my first and so far only Frontlines battle was over in ten minutes because we steamrolled the enemy and pushed them right back to their spawn.
That must have been grueling. My longest match in the BF franchise is BF4 Metro CTF. It was just about two hours long and holds my record for most kills in a match which I believe was around 240 kills with about 113 deaths.
