Bars are shown relative to the strongest structure of its class (Guardian). 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

With the invention of high-temperature superconductors, the issue of devices operating on the principle of a Gauss gun became actual. The Sentinel DM gun was originally designed as a gauss cannon with a kinetic projectile. But numerous experiments and comparisons of firepower with two-chamber systems were still not in favor of laser ammunition. The project was first frozen, and later changed and improved. As a result of many years of refinements and improvements, the Sentinel DM Cannon has been repeatedly strengthened in terms of protection systems and firepower, and became the first in a series of mid-range anti-tank guns

Questions and answers

What is "Guardian MD" in Xterium?
With the invention of high-temperature superconductors, the issue of devices operating on the principle of a Gauss gun became actual. The Sentinel DM gun was originally designed as a gauss cannon with a kinetic projectile.
Which ships is "Guardian MD" effective against?
"Guardian MD" is most effective against: Death Star, Cruiser MF, Cruiser LF, Cruiser HF. The effectiveness multiplier by class comes.
Where to build "Guardian MD"?
"Guardian MD" is built on the planet after the required research. After a battle, defense partially rebuilds itself and does not turn into debris.
