BlackICE Historical Immersion Mod

In 1 collection by maverick
3 items

We aim to bring Hearts of Iron 4 to an all new level, making your game experience more immersive, historical and challenging.
Black ICE completely overhauls most national focus trees, changes game mechanics, adds in tons of events, technologies, units and much more.
While playing ahistorical will work, Black ICE mainly aims at improving the plausible historical experience.

Current BICE version: v8.0.3- Checksum: 75fa
Supported HOI4 version: 1.13.6

Supported game language: English ONLY (other languages will produce errors!)
Highly Recommended: Get the Black ICE GFX Add-on here, which adds images to all events.
Make sure to ONLY use Black ICE + Black ICE Gfx, as any other loaded mod most likely will cause issues. Even purely cosmetic mods have been known to cause problems.

- New and improved national focus trees for all majors and most minor nations
- Hundreds of new techs to research, including country-specific armor, aircraft, and ships
- Completely revamped naval system. Customize your ship classes or rely on premade historical designs
- Air War with realistic losses and improved gameplay
- Dozens of new battalion and support unit types
- Extended laws and politics that allow you to fine-tune your strategy
- Immensely detailed, all-new production system, which provides a much more detailed approach to unit equipment
- Events and decisions to completely immerse you in the game and the history it follows
- Improved AI across the board to provide for a more unique challenge

BlackICE Official Guide

Of course a project of such scope does not come without bugs, and we are truly thankful for any messages that bring them to our attention, either here or in the Discord.
Please keep in mind that this is a project we are doing in our free time, so keep it civil. Nobody is forcing you to play the mod. (Although we think you should definitely be playing it!).

Alas, a lot of issues and bugs are out of our hands, as they are a result of un-moddable assets from Paradox.

Go here for the official Paradox troubleshooting in case your game doesn't load, or if it crashes.[support.paradoxplaza.com]

Black ICE has and is being worked on by a lot of dedicated people, and many countless hours have gone into it.

Allies invade. They are not good at it, but they do land troops in France.

The mod is really huge and after it I can't normally perceive any mod on HoI4, but there is one thing that completely kills all the interest.
Allies don't do the landing in Europe (U.S. also dont attack Japan). It turns out, if the player does not play for the major nation of the Allies, the winner is always Germany. Because of this in the game, roughly speaking, you can ONLY play for the U.S. or Britain...
I suprised why no one noticed it..

@Raiko Nato counters are the preferred symbol for BICE. If you are gettin Soviet symbols then the prob is either a bad dl or that you are using other mods/ submods with BICE. Neither versionis designed for using "Other" mods or submods. It is either TEST or MAIN plus the BICE Gfx submod. Nothing else.
