The combined game contains all of the content from IV and V, as well some additional quests, and is known as World of Xeen. In 1994, NWC released an enhanced World of Xeen CD, which expanded the amount of digital speech in the game.

The combined World of Xeen game contains a series of additional quests providing an epilogue to the events of Might and Magic IV and V. After Sheltem is defeated the party is summoned to the Ancients' pyramid by the Dragon Pharaoh to complete the quest that Prince Roland had been on all along: the uniting of the two sides of Xeen into a single, continuous world. Once the remaining quest lines are completed, Roland and Queen Kalindra are wed in a ceremony[5] that invokes the world's transformation.

MacUser named World of Xeen one of the top 50 CD-ROMs of 1995, and gave it a score of 3.5 out of 5.
