This is such a fun event. It adds an extra challenge to military tunnels and a puzzle that everyone gets excited to complete. Cahnu is amazing with customer support and quickly fixed an issue I had with an update. Definitely recommend! 

This is a great event for pvp or pve. Adds quite a challenge for players to complete. 

For an extra difficult time, use brad tiers plugin to make them random tiers for players to have an even funner/rage inducing time >:)

Would recommend.
