Portugal’s unique ability, “Casa Da Índia,” significantly increases the yields of International Trade Routes, but limits those routes to cities on the coast or with a Harbor. This ability also grants Trader units additional range and the ability to embark on water tiles as soon as they’re unlocked. Includes the Portugal civilization with João III, the Nau unique unit, and two unique structures, the Navigation School building and the Feitoria.

Joao

Joao’s unique ability is “Porta Do Cerco,” which grants all units increased Sight. It also increases Trade Route capacity whenever Portugal meets a new civ and provides Open Borders with all city-states. Portugal’s unique unit, the Nau, is a naval melee unit that replaces the Caravel. It starts with one free Promotion, requires less maintenance than the Caravel, and has two charges to build Feitorias, special shipping ports unique to Portugal.

Unique Infrastructure

Portugal’s unique building, the Navigation School, replaces the University building and increases Production toward naval units in each city that builds it. It also increases a city’s Science yields for every two coastal or lake tiles within the city’s borders and grants additional Great Admiral points. The Feitoria can only be built by a Nau unit on a foreign city’s coastal tile next to a luxury or bonus resource. Sending a Trade Route to a city with a Feitoria provides Portugal with additional Gold and Production.

New “Zombies Defense” Game Mode

The Portugal pack also introduces the new Zombies Defense game mode. In this optional game mode, the dead don’t stay dead for long and present an ever-growing threat to the world’s civilizations. The Dead Don’t Rest: Every unit has a chance to respawn as a ravenous Zombie when it dies. Zombie units hunger after and attack the nearest non-Zombie unit; any units they slay succumb to the infection and respawn as Zombies themselves.

New map script and new World Wonders

The Portugal content pack also includes a new map script and two new World Wonders. Squelch your way to victory through a soggy map dominated by Marshes. This map offers new strategic challenges and defensive possibilities: while Marshes penalize Movement, careful positioning can allow ranged units to exploit enemies’ reduced speed.
