Team Statement

Hello everyone! First off, thank you to everyone who has recently switched over to the beta branch to help us test out our new and first linear campaign. With this major update, we feel it’s ready for everyone now, so thank you for your patience in waiting so long for our newest update.

The changelog is quite large, but to highlight a few of the big features:

Whales are now a feature to help make submarine combat a little less straightforward. Now you’ll have to watch your fire!

Many environment and VFX changes (Sea foam, wakes, and biome changes primarily) as well as an overhaul of the atmospheric fog

Our first linear campaign series

Explicit sensor control and improved control over torpedo attack depth (right click on weapon on bottom bar to see options, only applies to ship mounted launchers)

And more than a month worth of bug fixes!

Some of the up and coming goals we have are to

Improve gunnery realism

Tutorial missions

Prepare for our first internal prototype of our AI infrastructure testing

And moving trees into autogen system, which could lead to more additions to it to help make the game environment more realistic and varied plus should improve the overall performance

Note on new mod compatibility check

Update 0.4.0 adds new functionality to check the base version compatibility for mods within the game install. Please note that this requires mod makers to add base version compatibility into their mod’s _info.ini file. At this time, most mods will not include this marker and so will appear in the list of incompatible mods. You can safely “Ignore” the warnings for now.

For mod makers: please follow the directions here to update your mods so this error is not thrown.

Check out the detailed change list below!

Today I beat the NATO part of the campaign It plays a little like World in Conflict did all those years ago. You play NATO in one mission and then Pact in the next. But at some point you are made to choose which coalition you will lead to victory. The missions are completely independent scenarios in expectable locations (Like GIUK, Pacific Islands). I found the mission design to be quite solid although you’re given plenty of hints on where to look. There’s still some things that feel a bit off with this early access game, like AIM-54 and AIM-7 having terrible Pₖ against AShMs at high altitude (even the AIM-9 was doing better! at angels 80) and enemy air power hyperfocussing on my AWACS resulting in them turning into Tomcat food.
