A substantial update for Hearts of Iron IV has been released today, taking the game to version 1.1. Dubbed ‘Red Ball Express’ (named after an allied truck convoy system), it includes numerous tweaks and changes to the AI, bug fixes, and some additional features.
The former can be read about in detail thanks to the extensive changelog replicated below. Feature-wise, players can now tell their command groups to execute plans “carefully”, “balanced” or in a “rush”. And, much to the delight of many, it’s now possible to design a division from scratch by choosing ‘new’ in the drop-down template menu.
AI-controlled opponents will be more likely to grant military access for those fighting a common enemy too. Plus, as noted in the headline, Hearts of Iron IV will only kill off King George V once now. Instead of twice, as sometimes happened pre-patch.
Here’s that mega changelog for patch 1.1.
– It is now possible to set a command group to execute orders in different manners: carefully, balanced, and rush.
