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 fight together cooperatively to defeat the increasingly strong AI horde and defend the Virgin (Allied NPC).
Players that defeat all waves of AI including the final tincan and hero waves receive a massive XP reward.
