This mod is mainly focused on vanilla aspects, especially offense/defense and alternative energy generation.
I take balance very seriously. Everything in this mod was carefully edited to be as balanced as possible for an authentic vanilla feel.
If my job is done correctly, you shouldn't even feel that any mod was installed. Everything fits in with the base game naturally, all the art is derived from the original game.
If something feels out of place, please leave a comment.

This mod is back and has been overhauled!

This mod expands on some vanilla aspects that I find that are too limited. It does nothing fancy, but adds some items that I feel that could be vanilla.

What this mod adds:
4 types of walls + 3 more types of gates. (Iron, Concrete, Plastic, Composite)
2 Advanced solar panels + advanced energy accumulators, each with their own use case
Wind turbines and tidal generators
Sonic tier of belts/splitters that are faster than express (and more expensive)
Oxygen furnace that is faster than electric furnaces but uses oxidizing agent instead of electricity
Electric boiler to store excess electricity back into steam (for people that like using renewable energy and would like to store large amounts of power as steam)
Thermal power plant that functions similarly as Nuclear power plant but uses combustibles instead of uranium.
Low power heat exchanger, exchanges heat to produce steam at 165C. Use with the Thermal power plant or if you want to use steam engines instead of turbines.
A Radioisotope thermoelectric generator that generates power forever, but at very low power.
A fusion power plant, much stronger than nuclear power. Should feed all your clean electricity needs for the late game.
A few more vehicles (Flak tank, Mortar carrier, Armoured car, Main battle tank, Cargo vehicle)
Corrosive ammo for guns, shotguns and tanks
More ammo types for guns
New guns (Assault rifle, light machine gun, gatling gun)
A first aid kit
Thermonuclear bomb (aka Hydrogen bomb, much stronger than the atomic bomb, for the end game)
Nuclear/Thermonuclear versions of artillery shell (Maybe too OP)
Artillery damage research
Finally a lot of new techs to research in order to unlock these advanced items.
And maybe some stuff that I forgot to list here. Since this is used on my private server with my friends I tend to add stuff here and there and forget about it.
