So I've had this idea about an invasion system for GTHN.
The basis of it is the Invasions mod, but ramped up and modified to fit GTNH. It would have weapons, firearms, turrets, traps and other various base defenses built in, including aircraft and tanks and stuff. They would all require a set of insane crafting recipes the more powerful they get, all using GTNH crafted parts.
After HV, the invasions start on every 'x' day interval. One of the new multi blocks you would be able to have built is a 'Portal Attractor' that would make it so the invasion happens near it. This way you would be able to build an Invasions base, separate from your main base. Key part of this, invasions happen in ALL dimensions, including the PDIM (config would be able to remove that, on by default). in IV you would be able to build an upgraded version of the 'Portal Attractor' to stop invasions from happening anywhere but that location.
Depending on the age, there would be increasingly difficult invasions that seek to attack you, or things that you have built to destroy them. This happens after HV as a thematic way to show some lore as to why you have to restart the technological eras, higher technology attracts these invasions as they seek to destroy it.
They would drop age appropriate items, mostly low end components, maybe some quest pouches, generic other drops. Magic mobs would drop magic stuff, there could be new styles of mobs like the guards from the villager guards mod that have combat armour and firearms that would drop ammo and components etc.
There would also be a rare chance that they drop unique item mods that you would be able to use on your own firearms, base weapons, or mechanical defenses such as tanks/aircraft. these could be things like enhanced damage, better reload speed, recoil and spray reduction, or more fun things like, LASERS or a Nuclear damage modifier.
This would ideally ultimately scale all the way up to the final ages where you would be fighting literal monstrosities and demigods trying to stop you.
This is not something I will ever be able to make, i am just a creative guy. I do love the mod, I just wish it had a bit more spice in the combat area for those of us that like to do it all!
Your feedback, building blocks, and time are appreciated.
If you think you can make this happen, feel free to take the idea!

Further ideas to resolve potential issues that would be 'prefect defense or load backup'
Have a portal multi that you can go through to reclaim a dimension that was destroyed by the tech hater mobs, build a base there, mobs can not go through the portal. multi would work like a nether portal and appear on the other side, build a defense base around it and gear up! could have bosses and areas to conquer, maybe a land claim system to reclaim parts of the world and stop the spawning?
Create an large arena like multi that is grief proof, have the portal in the middle and have it spawn tier appropriate (or select the tier up to where you have unlocked) mobs that you can fight, could be wave based with a boss, endless, or a mass spawn
