v24 Full Changelog (Trains, Factories, Upgradable Buildings)

Major New Mechanics

• Train System: Factory → Train → runs along rails between City / Factory, paying out gold based on the relationship of stations visited (allies 35k / team 25k / self 10k). Currently only available in single-player / private lobbies.
• Upgradable Buildings: City / Port / SAM / Silo all support 4-level upgrades (Factory introduced at the same time).
• Multi-level Radial Menu: The right-click build menu has been reworked into a multi-level dynamic structure.
• Flares System: Used to communicate intent (markers, warnings).
• Hash routing: URL routing rebuilt with hashes for easier deep linking.
• GitHub Releases sync: The in-game “What’s New” button links directly to the official releases.

Key Balance Changes

Item	Old	New	Impact
Trade Ship global cap	Unlimited	150	Diminishing returns on port count; port upgrades become important
MIRV	Powerful	Nerfed outer ring, can be quickly recovered	Psychological warfare > physical damage
Warship target priority	Warships	Transports prioritized, instant cooldown on hit	A single warship can shut down a sea invasion
Discounts	Reusable multiple times	Single-use	Stingy early-game build economy
AI Nukes	Any target	Actively avoid SAMs	A single SAM provides deterrence

Combat Experience Improvements

• Optimized territory drawing performance.
• SAMs only lock onto nukes near threatened zones (avoiding pointless shots).
• Nuke speed 4 → 6, shrinking opponent’s reaction window.
• Nation city building cap fixed (tryout33).
• Team size auto-balancing.
• MIRV warhead intercept stats now credited.
• Terrain manipulation mechanic (affects mag/speed).
• Red “betrayed” border indicator (devalnor).
• Attack and transport ship hotkeys (Engla).

UI / QoL

• Leaderboard reworked, performance optimized.
• Modals / alerts support translation and dark mode.
• Custom flags and patterns (sword, skull, white rabbit, goat, radiation, cursor, QR, etc.).
• Top bar redesigned (Diessel).
• New building icons / build / HP / reload bar styles.
• Global color reassignment to avoid same-color player confusion (Ble4Ch).

Backend / Technical

• Stats endpoint opened publicly.
• CORS Origin added.
• Native mobile login support.
• Discord user and guild caching.
• Improved session error handling.
• CC BY-SA resource license attribution.

Strategies Players Should Adjust

1. Port strategy shifts to “upgrade rather than build new” — the 150 cap causes marginal returns on the 5th+ port to plummet.
2. Sea invasions require clearing the seas first — a single warship can massacre transport fleets, so send 2-3 warships to clear the lane before landing.
3. Build your first SAM earlier — AI now avoids SAM coverage, drastically lowering the deterrence cost.
4. Treat MIRV as psychological warfare — spend 25M gold to disrupt opponent deployment rather than expecting kills in the outer 18 tiles.
5. Ally rails = economic leap — in a 3-player alliance, building 2 Factories + sharing connected Cities can send income soaring.
