Civ 6 spring update tweaks Joint Wars, adds 12 Historic Moments

Besides Victoria's England-strengthening Pax Britannica leader bonus, Civilization 6 now lets players call for help mid-battle. 

As part of the turn-based 4X 'em up's spring update, new diplomacy tinkerings to Joint and Third Party War means players can now ask others—be that pals, strangers or AI—to join battles they're already engaged in.  

"There's been a lot of discussion in the community about Joint Wars. These rules have been updated," says lead designer Anton Strenger in the video below. "First, Joint Wars may be declared using a Casus Belli, which will require a denouncement from at least one of the players. Second, AI and players can join wars that have already begun, and gain the benefits of the Casus Belli that are in effect." 

Over to you, Anton:

Further to that, Joint War now requires one party to have denounced their enemy for five turns, so says this Steam Community update post, while the leader screen now clearly identifies that war declaration is part of a joint engagement.  

Above, Strenger addresses the yield discrepancies identified by Tyler in March, noting a "general all around improvement in AI scores." 

Civ 6's spring update also adds 12 new Historical Moments—from the World's First City with 25 Population, to the World's First National Park and World's First Seaside Resort—the sum of which can be perused here.
