Total War Saga: Thrones of Britannia players can now download the "Blood, Sweat and Spears" pack, which, judging by the footage and screenshots below, is a very explanatory title for what's included with the new content.
It adds plenty of gore but what might be even more juicy, is that the content comes along the Allegiance title update, which tweaks and improves several areas of the game based on community feedback. This means changes to politics, combat AI and, according to the PR, "a new system for issuing decrees", but the titular Allegiance is the main new feature, as it's all about loyalty conflicts when it comes to invading new lands.
Blood, Sweat, and Spears can be either purchased on Steam or downloaded for free by those who own Blood & Burning pack for Total War: Attila.
