Hello adventurers, After the overwhelming response we received yesterday with the Sands of Ulminin DLC, we have been talking with Paradox and following the spirit of their other games, we have altered the game and DLC to removed the restriction that all party members need to have the DLC to enter Sands of Ulminin. Now, in multiplayer, players without the DLC will be able to access the new zone as long as one of the players has the DLC, they will be able to play as normal, buy the new items and unlock the new heroes and pets; however, to be able to play with those heroes or pets, it will be necessary to own the DLC. From now on and for the following DLCs, only one member of the group will need the DLC to enter the new zone. This will also work retroactively with the Wolf Wars DLC. With regards to the Sandbox mode. This is the first iteration of this awesome new feature that allows you to change a lot the behavior and the "normal" way of playing the game. Over time we will be improving this mode, adding more options and adapting it to other game modes such as the Obelisk challenge. Still, bear with us if you find any strange combination that doesn't work exactly as it should (for example, single hero games in some events), please report it to us in the discord so we can fix it as soon as possible. As always, thanks for your feedback and support. - ATO team.
