The Eruption Campaign (Alternate History)

Dec 15th, 1985. Yellowstone erupts. The United States is in chaos.

With the Rocky Mountain states and the Midwest effectively destroyed, the West Coast is forced into self-governance until communication can be established with the Federal Government in the East. When contact was reestablished, rather than being offered aid, the Reagan administration chastised the Western states for administering themselves. The starving US military personnel stationed on the West Coast were then ordered to begin quelling the “insurrection.” Having gone without pay, leave, or even consistent food rations for months, the soldiers and sailors are outraged that they are now being tasked with killing their fellow Americans. Led by a cabal of high-ranking officers and politicians from the Western States, the revolution begins, culminating in the Governor of California declaring independence July 4th, 1986.

This campaign consists of 6 scenarios, with 3 taking place during the Western Revolution in 1986, and 3 taking place during the early 90’s as the Republic of California, Confederation of Cascadia, and Kingdom of Hawai’i are still embroiled in a low-intensity conflict with the US. After the US’ success during Desert Storm and Desert Shield, they are emboldened to start acting more aggressively towards the West Coast. I tried to make these scenarios both interesting and challenging, while including a good mix of surface, submarine, and air operations across all the missions. You will be using American equipment against other American equipment, meaning that this will be a true test of your skill as a commander, since both sides will be relying on the same weapons. Each mission has a detailed briefing that explores the setting. If you find this sort of thing interesting, check out the “Eruption Universe” on YouTube, there’s plenty more AltHist nonsense to be had 😉

*KNOWN ISSUES*

-I’m using the Jolly Roger (Pirate Flag) to symbolize the fictitious West Coast nations. This causes an error message while loading the mission, however it doesn’t seem to have any effect in-game. Some of the status messages are kind of goofy because of this too. If/when I can figure out modding for this game I will create appropriate flags and add them.

-After the latest update AnchorChain, SeaLifter, and several other mods are also throwing up a bunch of error messages during loading. Again, the missions still seem to be working fine. Just click “Ignore” during loading. Hopefully they will be updated soon.

-Airbases spawning with autogenerated buildings on top of them; again, this is an issue with Sea Power itself. I made the decision to have the airbases located in the correct location geographically. In some cases I was able to move the bases to an open area nearby, however in some cases (Moffet Field, McChord AFB, and North Island NAS to name a few) the airbases are built in the middle of an urban area and I had no other option. Seeing as this is Sea Power and not Land Power I don’t spend much time looking at airbases unless I’m watching planes take off or land, so it doesn’t bother me personally. You can turn off autogens in the game options if it really bothers you.

-Seeing as towing/tugboats aren’t implemented in the game, you’re going to use your imagination a bit for the first scenario. Sometimes the ship under tow will break formation and do its own thing; not much I can do about that unfortunately.

-During the first mission you might have to launch recon aircraft to spot targets for you. This doesn’t really make sense lore-wise, as the rebels would know the location of their targets. Again, this is just how the game works for the time being.

-The S-70 helicopter and fictional F/A-7J sometimes get bugged when launching and recovering. You’ll have to take it up with the individual mod makers if you want this fixed. If this happens, you can use the debug menu (F10) “Self Destruct” button to clear the offending aircraft. The missions are designed with plenty of other aircraft available to you, so don’t need to use them if you would rather not be bothered.

*REQUIRED MODS*
-New Threat Upgrade
-Warsaw Pact Enhanced Lethality
-A-10
-Royal Australian Defense Forces
-MiG-29/F-16C
-F-16A
-AH-64
-Real World Airlines
-S-70B-2 Seahawk
-Arliegh Burke

I would also recommend “Air deck operations upgrade – NTU” by ossesek, however it is not required. Using it may also lead to issues with modded aircraft.
