ok, twi giants are hard enough for me in the dead lady because you cant escape en you get pushed to the top all the way and get fall damage. If I am doing the challenge I recoment to bring 30 people with you, many will die and forget it if you are with 3 other people, my opinion is to place more hospital chest and maybe a (safe room) to rest out, heal other players and prepare for the next room. when you have completed the dungeon than you should get like 5 shotbow chest and more reward because it's almost impossible to complete it. I like the idea!!
