New PVP Mode - Team PVP!
I'm sure this has been requested before, but team PvP would be a great way addition to the game.
Team PVP can be accomplished with a new type of Respawn Pad - Team Respawn Pads! You could buy them from the shop (each would be a different color) and place them. Team A would only respawn on Team A Pads, and Team B would only respawn on Team B Pads.
Upon entering a Team PvP arena, you would be automatically assigned to a team based on number of players, but you could switch to the other team with a command, i.e. /teamswitch. To prevent cheating, doing this would respawn you at the respective team telepad.
This is just the initial idea. You may want to consider adding timed Deathmatches or Capture the Flag in the future, but this is definitely a good place to start.
Have an 8-Bit day!
