Your team must to "Be first who active the temple" to win!
You need 5 redstone tourches for active the temple, and after you put it all the temple activation have a delay to can be stoped.
You must protect temple in this time, is not a big delay.
These 5 redstone tourches can be finded just in chests, and at start each team have a tourch bonus "hiden" in buncker base.
So in chests are just 3 tourches.
Near the each buncker you will find chests with items which must be divided with your team.
You can play it from 1vs1 at 5vs5, but i recommend 5vs5 or 3vs3.
I hope you and your friend will enjoy it!
