Open Beta Announcement Open Beta Update I

Best to leave your feedback for this specific beta version in this thread. Bugs go in the bug report forum. You can also start a separate thread, just make sure to reference this open beta and mention something like [open beta] in the title.

I’m Zwirbaum, Game Designer for Hearts of Iron, and this time around Open Beta arrives a little bit earlier - on Thursday, instead of the usual Friday! (Good Friday in Sweden is a Bank Holiday). Because of the faster release of this update than normal, this means that it will spend less time in the oven than usual. Most of my focus right now will likely continue on tweaking the submarines, and their detection & stealth mechanics. I would gladly appreciate letting me know - how does the balance feel when using or fighting against submarines? (Of course ideally after trying out Open Beta Update II).

Responses to my question last week were definitely interesting, and gave me a lot of things to think and ponder about - on the topic of the hyperspecializations vs flavourful / more-multi role designs. Thanks for the answers and discussions you created on this topic!

I wish all of you a Happy Easter/Holiday if you do celebrate it, otherwise have a great weekend everyone! :)

Thanks for reading, and until next time, farewell!

Open Beta Update II Notes (Changes from previous OB build to current OB build)

Gameplay

Submarine Detection Formula Tweaked

• SUBMARINE_REVEAL_DETECTION_MULTIPLIER reduced from 0.1 to 0.075. This reduces the passive reveal chance for submarines in combat by around 25%

• SUBMARINE_REVEAL_TORPEDO_FIRING_DETECTION_MULTIPLIER increased from 1 to 1.1. Submarines firing Torpedoes will have a higher chance to be revealed in combat by around 10%, unless they have Torpedo Reveal Chance modifier. Submarines firing torpedoes without any modifiers should be ~17.5% less likely to be detected than in previous Open Beta Update.

• SUBMARINE_HIDE_TIMEOUT reduced from 20 to 8. This means that the submarine after being revealed will stay visible for 8 hours instead of 20.

• SUBMARINE_REVEALED_TIMEOUT reduced from 16 to 12. This means that if the submarines are on the defender side (their taskforce was attacked) - they will stay revealed at the start of the combat for 12 hours instead of 16.

• SUBMARINE_REVEAL_ON_MINIMUM_POSITIONING reduced from 2 to 1. This means that on 0% positioning Submarines will get +100% Visibility instead of +200% Visibility

• Shallow Waters now increase Submarine Visibility by +33% instead of +100%.

Developer Commentary: Purpose of these changes is to reduce overall how often submarines are detected and sunk. With them spending less time revealed, they may actually have a chance to escape heavily damaged instead of being in 99.9% cases destroyed. The detection rates are also reduced a bit, while on top of that reducing the impact of 0% positioning and shallow waters on the submarines. Low Positioning Penalty and Shallow Waters was especially crippling for the early submarine types as they start with a relatively high visibility, thus +100-300% swing can mean between going from ‘25’ visibility to ‘50-100’ visibility, while later submarine types, especially equipped with better modules and/or having MIO Traits would see their visibility barely increased in the absolute numbers.

Early Submarine Hull Sub Visibility 25 → 22 Strength 10 → 15

Basic Submarine Hull Sub Visibility 22 → 20 Strength 20 → 22.5

Improved Submarine Hull Sub Visibility 20 → 18

Advanced Submarine Hull Strength 35 → 37.5

All Carriers (Carrier Conversions, Escort Carrier, Basic, Improved, Advanced, Modern and Ice Carrier Hulls) Surface Detection 26 → 20 Sub Detection 5 → 1

Carrier Deck Space Module Carrier Surface Detection 5 → 8 Carrier Sub Detection 2 → 4

Ice Carrier Deck Space Module Carrier Surface Detection 6 → 10 Carrier Sub Detection 2 → 4

Escort Carrier Deck Space Module Carrier Surface Detection 2 → 5 Carrier Sub Detection 5 → 7

Aggregated Patch Notes (*Changes from Live to current OB build)

Developer Commentary: Carriers will no longer enjoy the ‘free’ extra 4 points of Sub Detection and 6 points of Surface Detection, compared to most of the other ships. Their deck space modules however have been powered up, thus providing higher bonus to the Surface and Sub Detection, granted that the Carrier has planes on them. For both Escort and ‘Regular’ Carriers, two decks with full flight compartments will be enough to offset the loss of the ‘free’ Surface Detection and Sub Detection, while any extra deck will provide increased detection stats over the previous stats. It does however make the deck modules even stronger for the time being, thus making them even more “hyper specialized”. We will see in the future if it is possible to make their alternative options more enticing.

• Naval Reform Spirit was changed from +15% Naval Experience Gain to +10% Naval Mastery Gain (This was actually done last week, but I forgot to add it to the Patch Notes)

Gameplay

• Reworked submarine detection formula, added three new defines related to the submarine detection, SUBMARINE_BASE_STEALTH_VALUE, SUBMARINE_REVEAL_DETECTION_MULTIPLIER, SUBMARINE_REVEAL_TORPEDO_FIRING_DETECTION_MULTIPLIER

• SUBMARINE_REVEAL_DETECTION_MULTIPLIER reduced from 0.1 to 0.075. This reduces the passive reveal chance for submarines in combat by around 25%

• SUBMARINE_REVEAL_TORPEDO_FIRING_DETECTION_MULTIPLIER increased from 1 to 1.1. Submarines firing Torpedoes will have a higher chance to be revealed in combat by around 10%, unless they have Torpedo Reveal Chance modifier. Submarines firing torpedoes without any modifiers should be ~17.5% less likely to be detected than in previous Open Beta Update.

• SUBMARINE_HIDE_TIMEOUT reduced from 20 to 8. This means that the submarine after being revealed will stay visible for 8 hours instead of 20.

• SUBMARINE_REVEALED_TIMEOUT reduced from 16 to 12. This means that if the submarines are on the defender side (their taskforce was attacked) - they will stay revealed at the start of the combat for 12 hours instead of 16.

• SUBMARINE_REVEAL_ON_MINIMUM_POSITIONING reduced from 2 to 1. This means that on 0% positioning Submarines will get +100% Visibility instead of +200% Visibility

• Shallow Waters now increase Submarine Visibility by +33% instead of +100%.

• Reduced minimum naval hit chance from 2% to 0.5%
