Lustre

Lustre is a heavy turret-class block that fires high-damage nitrogen-based ammo and requires only electricity and Electric Heaters to operate; it does not consume items from inventory. Introduced in Build 136, Lustre was later adjusted in Build 147 to draw 200 power units/second and to increase its nitrogen ammo damage (1800 → 1890/sec, 200 → 210/tick).

The turret excels at dealing extremely high single-target damage, making it an effective choice for cutting down powerful individual enemies such as large ground vehicles or single strong mechs. Because its ammunition is supplied by nitrogen heaters rather than conventional item inputs, Lustre can be placed anywhere on the map as long as you can provide sufficient carbide for heater production and enough continuous power (or batteries) to sustain its high draw. Lustre’s lack of item input also allows it to share nitrogen supply with production structures like Prime Refabricators with little to no conflict when those structures are not continuously running.

Despite its raw power, Lustre has important tactical limitations. Its slow rotation speed and targeting priority cause it to focus on high-health tanks that may be shielding smaller, more dangerous attackers; this makes it vulnerable to swarms and multi-directional assaults. It performs poorly against missile-based units and is completely countered by the Collaris. Because Lustre is optimized for single-target bursts, it cannot match the area or multi-target suppression of more flexible turrets such as Afflict. Placing Build Towers on or near Lustres can strengthen static positions, and pre-rotating (firing early so the barrel faces the expected approach) helps it start dealing damage sooner as enemies arrive.

Practical notes for deployment and use:

• Provide stable, high-throughput power (including batteries) to satisfy the 200 power/sec requirement; Lustre’s effectiveness collapses if power is intermittent.
• Supply sufficient Electric Heaters (and carbide) to keep nitrogen ammo available; the turret does not pull items from chests but relies on heater output.
• Situate Lustres to cover choke points or to guard high-value targets where single-target damage is most useful, rather than open-field swarm defense.
• Combine with other turret types or area-denial defenses to handle swarms, missiles, and flanking attacks that exploit Lustre’s slow tracking.
• Consider pre-firing to orient the turret toward the expected enemy path so it can engage immediately.
