That One Thing
One shared map can turn a quiet evening into a week-long argument about who stole the best castle.
Horn of the Abyss (HotA) is the gold standard expansion for Heroes of Might and Magic III: Complete. It introduces two fully-developed new factions (the piratical Cove and the industrial-steampunk Factory), original story campaigns, simultaneous turns for multiplayer, an active built-in online lobby, naval battlefield mechanics, new neutral creatures, and tournament-caliber balance.
