This is my second idea, it's call Hardcore Capture the flag. So there are 4 teams with 4 people in each team and everyone has a flag. But the twist is that you have to GET stuff. You don't start off with anything and you have to mine and get your stuff the hard way. Everyone has 15 minutes to prepare for the walls to drop. Also, players can break and destroy blocks before the walls drop and after. So each team's goal is to bring an other teams flag to a flag capturing point. But the thing is, people from other teams can build on other team's ground. So another team could put Oby around the flag capturing point. Also, if you die, it's keep inventory and you respawn. But if your flag got captured, there's no respawn. The last team alive wins! That's what I got so far, I hope you like it. Any improvements I can add?
