Armor Weapons and shields and the future of depth in combat

When we talk about ship combat in a game like Space Engineers 2, durability shouldn’t just come down to how many hit points a block has.

Instead, ship survivability should come from three core systems working together: armor design, shield engineering, and the way weapons interact with those systems.

The goal is to make combat feel less like shooting health bars, and more like fighting real engineered spacecraft.

Let’s start with armor.

In Space Engineers, armor already exists in two materials: light armor and heavy armor, and in two grid scales: small grid and large grid. These differences can naturally represent different levels of protection in a penetration-based damage system.

Light armor works well as structural plating. It’s lightweight, inexpensive, and great for shaping hulls or building internal framework. But it shouldn’t stop serious weapons. Most kinetic rounds should be able to punch through light armor unless it’s angled or layered.

Heavy armor, on the other hand, represents dense protective plating. This is the kind of armor you would place around reactors, hydrogen tanks, ammunition storage, and bridge sections. It should be significantly harder to penetrate.

Grid size can also represent physical thickness. Large-grid armor naturally represents thicker structural sections, while small-grid armor provides lighter protection suited for smaller craft.

But armor isn’t just about material. Geometry matters too.

Space Engineers already gives players wedges, slopes, and corner pieces, and these shapes could influence how weapons interact with armor.

Flat armor provides consistent protection but offers little chance to deflect incoming fire. Sloped armor increases the likelihood that projectiles will lose penetration energy or ricochet. Carefully shaped hulls could effectively increase armor thickness and deflection angles.

This means ship protection wouldn’t just come from stacking blocks—it would come from how you design your ship.

Now let’s talk about shields.

Instead of being a simple health bar, shield strength should depend on three main things: emitter size, emitter quantity, and total power input.

Shield emitters would come in multiple sizes and would scale with the amount of reactor power supplied to them. However, they wouldn’t have unlimited efficiency. The more power you push through an emitter, the less efficient it becomes.

This encourages players to spread shield generation across multiple emitters instead of relying on a single oversized generator.

Each emitter would also protect only a portion of the ship.

For example, a small emitter might cover roughly twenty-five meters of hull area around where it’s installed. A larger ship would therefore need multiple emitters distributed along its structure.

If you had a ship around seventy meters long, you might need an emitter near the bow, another near the stern, and one near the center. Depending on the height of the vessel, you might also need emitters on the top or bottom of the hull.

This turns shield placement into a real engineering challenge.

Another important mechanic is shield projection distance.

The larger the emitter and the more power you feed into it, the farther away from the hull the shield projects.

Small emitters create shields that hug the ship’s surface closely. Larger emitters generate shield bubbles that extend farther out.

This has an important gameplay consequence.

When a shield sits farther away from the hull, it creates space between the shield and the ship itself. Smaller ships, fast strike craft, or specialized torpedoes could potentially slip inside the shield bubble and hit the hull directly.

This prevents shields from becoming simple damage sponges and adds interesting tactical opportunities during combat.

In terms of balance, smaller ships with shields would have lower overall shield durability, but their shields would sit very close to the hull, tightly following the ship’s outer shape.

Larger ships would have stronger shields but larger gaps between the shield surface and the hull, creating opportunities for shield bypass attacks.

Smaller emitters would also recharge faster, while larger emitters would provide greater protection but recharge more slowly and require significantly more power.

Now finally, we get to how weapons interact with all of this.

Weapons shouldn’t just deal raw damage. They should behave differently depending on penetration, deflection, and explosive interaction.

For example, explosive weapons should interact with armor realistically.

If a missile detonates against spaced armor two meters away from the hull, and the blast radius is three meters, the explosion should destroy the outer plate but fail to damage the hull itself.

That means spaced armor becomes a meaningful defensive system.

Kinetic weapons would interact with armor based on angle and penetration capability.

Gatling guns might penetrate thin armor but bounce off heavy angled plates. Autocannons could punch through medium armor but deflect at shallow angles. Railguns might penetrate multiple layers of armor entirely.

This creates a rock-paper-scissors relationship between weapons, armor thickness, and ship design.

A well-engineered ship might have a thin outer hull, spaced armor plating, and internal armored compartments protecting critical systems.

In combat, missiles could blow away the outer armor while leaving the hull intact. Smaller weapons might bounce off angled plating. And heavier weapons could punch deep into the ship until they finally reach something critical.

The result is a combat system where engineering matters.

Ships survive not because they have the most health, but because they were designed intelligently.

And in a game about building spacecraft, that’s exactly what ship combat should reward.
