The upcoming Civilization 7 update, version 1.3.0, will significantly overhaul naval combat, introducing a system referred to as 'naval combat 2.0.' This update will categorize naval units into two types: Light Units, which are fast and melee-focused with increased vision, and Heavy Units, which are slower but capable of powerful ranged attacks. The update will reintroduce true ranged combat at sea, recalibrating melee and ranged strengths to align with these new roles. The new Privateer unit will allow players to ignore borders and pillage trade routes, impacting diplomatic relations. The update also includes the Civilization 7 Tides of Power collection, featuring new leaders, civilizations, and wonders, available for free for a limited time.
