Halcyon Arc Systems: Energy Turrets

Three energy turrets for large and small grids. No ammo: they run on your ship's power. A weak grid makes them fire slower, but they never run dry.

They cost more to build and they are hungry, but you won't be hauling crates of shells for them.

The turrets

HAS-F2 Fangs, twin plasma turret Large grid 3x2x3, small grid 5x3x5. Bolts fly 1000 m and fade after 800, auto-aim 800 m (small 600). Up to 8 MW while recharging (small 2 MW). Two barrels firing plasma bolts in pairs, about twice the damage per second of the assault cannon turret. Strong against: ships at medium range, armor. Weak against: fast fighters, anything past a kilometer.

HAS-R6 Revolver, rotary energy gatling Large grid 3x3x3, small grid 5x5x5. Range 800 m (small 600). Up to 4 MW (small 1.5 MW). Fires 720 rounds a minute for as long as you hold the trigger, with no pauses to reload. A six-cell drum spins up instead of barrels. Strong against: missiles, fighters, drones. Weak against: heavy armor.

HAS-L1 Lance, charged beam turret Large grid 3x2x3, small grid 5x3x5. Auto-aim 1000 m (small 800), the beam reaches 2000 m (small 1400) when you aim it yourself. 10 MW while charging (small 2.5 MW). Charges for ten seconds, opens the petals on its muzzle and fires one beam that arrives almost instantly, dead straight, with no spread. About the artillery turret's damage per second, and no leading the target. Strong against: big ships at long range, armor. Weak against: swarms and anything fast up close. It fires once every ten seconds.

The sight

Take control of any of them and you get its own sight: the charge, the power draw, a range finder and the name of what you're aiming at, colored enemy, neutral or friend. The Fangs show which barrel is loaded, the Revolver spins its drum and shows its rate of fire, the Lance shows the time to a full charge and how long the beam will fly. Tab hides it with the rest of the HUD.

Colors

Each turret has a Shot color setting in its terminal, right below AI aiming radius. It recolors that turret's shots, hit flashes, the glow on the turret and its sight, so every battery can wear its own color. Select several turrets to paint them all at once. Only the hue counts, the shots always stay bright. The color is saved with the block and in blueprints, and Default color brings the Halcyon magenta back.
