cRPG is a modification for Mount & Blade II: Bannerlord. It adds persistent multiplayer character stats, hundreds of unique items, an online campaign, clans, duel ladder, a co-op game mode and a few more things.
Players on the Official China 1 Battle server defend the flags on a castle map.
Flags appear on the map when either team falls to less than 7 remaining players alive. They can also appear randomly.
To raise your teams flag you must be the only team in the radius. When your teams flag reaches the top you win!
