Dwarf Fortress' Siege Update has finally arrived, representing the first major evolution of Bay 12 Games' inimitable management sim since its triumphant arrival on Steam. Up until February this year, the focus of brothers Tarn and Zach Adams was on catching up with the ASCII version features-wise, culminating with the launch of Adventure Mode. Now that's done, the duo are wholly focussed on doing what they do best—embellishing their already preposterously detailed simulation to make it more involved than life itself.
The Siege Update represents the first step into the Steam version's new frontier, designed to make invader attacks on your fortress more dynamic and strategically nuanced. Prior to the update, goblin hordes could only exploit existing gaps in your defences, making it relatively easy to funnel enemy incursions into deathtrap-filled gauntlets. From now on, though, invaders will effectively lay siege to your Fortress, actively seeking to destroy your defences using more sophisticated tactics.
