I just recently made a new personal record in arras.io siege mode. My final score was 1.5M. After a long 30 minutes of fighting celestials with my not-so-smart teammates, the bosses finally destroyed us. ALSO THIS ALL HAPPENED IN ONE GAME :D Mobile friendly click to advance you know the drill
Backstory: Siege mode is a gamemode where waves of bosses will flood the small arena and try to destroy all of your teams sanctuaries. The sanctuaries are quite OP as they provide shelter and healing so it takes many many bosses to destroy one with players attacking the bosses. Once your team loses all of its sanctuaries you cannot respawn so the best thing to do is to revive a sanctuary by killing it yourselves.
