In the next chapter of the Escape Room bundle you can expect 4 levels with a lot to discover and solve. The 4 levels differ in difficulty.
Start on a lobby map where you can meet up with your friends. Here you can choose a character, make settings, spend the time with puzzles you've already unlocked in the Escape Rooms, and play a challenge or two with or against your friends.
Then, when you're all ready, start a level and the fun begins.
