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.
Here we see a mounted player has ridden quickly to the trap door activator. Getting there quickly he is able to stop a large portion of the enemy team before they even engage his team, sending them plummeting hundreds of feet to their deaths.
YES
One of the more effective uses of the trap door that I have ever seen.
