Stats
Bars are shown relative to the strongest structure of its class (Achille). Defense is static — it has no speed or cargo hold. "Weapon points" — one structure's contribution to combat power.
Effectiveness against fleets
"Rock-paper-scissors": a structure has its own effectiveness multiplier for each ship type. ×2…×5 — how much harder it hits a favorable target; ×0.5 — an unfavorable one. On top of that, combat applies rapidfire ×1.5 (a separate multiplier, it is not multiplied).
"Rapidfire" is a combat mechanic of the engine. More details — section Combat system.
Calculator: defense versus ship
Pick a structure and a ship — we'll show the defense's effectiveness multiplier against that ship.
Requirements
To build this structure, you need to raise the following to the required level:
Defense is built on the planet (the same place as the fleet). Technologies are leveled up in the Laboratory — section Research.
Description
The Achilles system is so huge that a factory is being built specifically for it. Giant monolithic slabs are mounted, as a rule, in rock on the shores of vast oceans. If the planet is uninhabited, resort to artificial storage. The cooling system is built separately: deep under water. The powerful gravity cannon is backed up by two side laser turrets. According to the characteristics, "Achilles" is an order of magnitude superior to all analogues. With the advent of this model, many experts began to talk about a new era in the design of super-powerful air defense systems.
