Just got back into minecraft after a long while and I'm trying to find an old game mode where 2 teams would face off (around 50 vs 50) and try to destroy the enemy's base. Not only were you able to fight pvp style but also build structures to help defend or attack. Similar to bed wars but there was no classes. Really enjoyed it from memory but I cant find anything like it anywhere.
That sounds like the one! Any servers running it with lots of players?
As far as I know there aren't, at least not ones with a lot of players. You could try play.stratus.network though, just know that they rotate game modes which means you might need to wait or play a bit before a DTC game starts up.
