This is very EA version!

Many planned features (game rebalance, other planet changes, etc) aren't done yet.
Requires Space Age DLC. I'll try to release a version for vanilla factorio at a later date.
I would love to hear all your feedback!

Mod endgoal - to make combat part of factorio interesting during all playtime, with steady difficulty level.

Designed as standalone mod.

Mod practically requires starting a new save, since it changes resource and enemy base generation!

Already done:

Resource and enemy bases spawn rework. (Enemy map-gen sliders will change spawner/worm amount per base)
Resources after depletion will leave infinite leftovers with higher mining time (oil patches reworked to be the same as other resources, pumpjacks have radius).
New script-based biter attack mechanic, they will try to attack conquered (or starter iron) resource patches. You can also make biter attacks more often during the night.
Worms at enemy bases are upgraded with evolution.
Pollution and Evolution levels rebalance.
Recipe changes (Solar panels, Space science and some other minor changes).
Nuclear energy was nerfed.
Modules rebalance.
Many combat rebalance changes.
Roboport building is a 2x2 size building now.
Early limited armor equipment and robots.
Recipe throughput fixes (endgame foundry recipes with liquids).
Technology tweaks (no double bonus for gun turrets!).

Features currently in testing, but not released in this version:

Bigger roboport building
