Immersive Mediterranean
Immersive Mediterranean for Hearts of Iron IV
The struggle for control of the Mediterranean Sea and its vital North African territories is a critical aspect of World War II. This mod aims to significantly enhance the strategic importance and immersion of this crucial theatre within Hearts of Iron IV. By re-evaluating the significance of key locations and introducing dynamic scoring and modifier systems, players will find the Mediterranean front a far more engaging and consequential battleground.
Elevated Strategic Objectives
The mod introduces a tiered Victory Point system, assigning different point values to capture and hold strategically vital locations. This encourages focused assaults and defenses on objectives that truly matter:
- Vital Targets (3 Points): Sicily, Sardinia, Tripoli, Gibraltar, Malta, Suez
- Advantageous Targets (2 Points): Benghazi, Derna, Crete, Cyprus, Alexandria, Cairo
- Discretionary Targets (1 Point): Central Albania, Dodecanese, Eritrea, Shewa, Somaliland, Aegean Islands, Peloponnese, Matrouh, Aswan, Khartoum
Capturing these locations directly contributes to your faction’s overall dominance in the region.
Dynamic Momentum and National Spirits
As the conflict in the Mediterranean unfolds, your faction’s performance will be measured against specific “Momentum Thresholds.” These thresholds, distinct for the Axis and Allies, trigger updates to faction-wide National Spirits. These spirits, ranging from minor advantages to major boons, directly reflect the ebb and flow of the Mediterranean campaign. Victory can bring increased stability, better production efficiency, and stronger naval forces, while defeat can impose significant penalties on morale and war support. The overarching score determines one of seven distinct National Spirits, from complete victory to utter defeat, profoundly impacting your nation’s capabilities.
Impactful Modifiers
The National Spirits directly translate into tangible in-game modifiers for Italy and the United Kingdom, as well as their respective puppets and allies. These modifiers can dramatically alter your nation’s performance:
- Axis Gains: Bonuses to stability, production, naval morale, and convoy raiding efficiency.
- Allied Setbacks: Penalties to stability, war support, army morale, and convoy escort efficiency, alongside potential naval fort construction speed increases.
- Allied Gains: Bonuses to stability, production, naval morale, and convoy escort efficiency, alongside potential naval repair speed and fort construction speed increases.
- Axis Setbacks: Penalties to stability, war support, core attack and defense, army morale, and naval repair speed, alongside potential naval fort construction speed increases.
These modifiers ensure that the outcomes of battles in the Mediterranean have far-reaching consequences for the war effort.
This mod is not compatible with achievements but is designed to be playable with the current version of Hearts of Iron IV and aims to remain up-to-date. Localization for additional languages is a community-driven effort, so feel free to contribute your suggestions.
