Improved Space Battles [Balance]

Improved Space Battles
5 items
Improved Space Battles - expand your mid / late game with 5 new super-capital class ships, over 50 new technologies and 11 doomsday weapons - including planet destroying, star system destroying and anti-fleet super-weapons.

Initial Compatibility Hotfix for 2.1. Sincere apologies for going MIA!

Improved Space Battles (ISB) attempts to improve both the visuals and gameplay of Stellaris's space battles. This is the standalone balance portion of ISB and contains gameplay changes designed to balance and encourage massive space battles. For the best experience, use this mod with Improved Space Battles [Graphics] which focuses on graphical tweaks for more epic space battles. This mod is designed for long games in huge (1000+) star galaxies. However you can lower the mod's difficulty for smaller galaxies through Empire policies.

Improved Space Battles is a mod that aims to : Speed up the early game. Encourage strategic wars in mid game by allowing players to build defenses that limit an enemy fleet's ability to just FTL past their entire border. Set up the end game for massive battles with other empires and galactic invaders. It also modifies fleet AI to make large battles less of a melee brawl.

Fallen empires, crisis events (ED Invaders, swarm, AI) and other end-game challenges are all massively buffed to ensure the game remains challenging and fun. Weapons overhauled to improve balance. Defensive stations HP/Armour greatly buffed and maintenance reduced to allow for more strategy during wars - beyond blind aggression. A ton more changes, full list in the change log.

IMPORTANT - You can adjust the difficulty of crises / FEs / AEs / Guardians at any point in the game through empire policies. Type free_policies into the console to freely change policies without a cooldown.

Can confirm: This mod is popping up empty event boxes every tick. Quite a few are doing this, actually.

If this mod doesn't get updated, it's dead.
