Fuse

Fuse is a short-range, close‑quarters turret that fires three piercing blasts in a spread each time it fires. Each shot is treated as a laser projectile with unlimited pierce, but the three-blast spread produces a shotgun-like effect that deals line-based area damage when targets are clustered or close to the turret. Fuse uses discrete ammunition items rather than power-fed shots; it currently accepts Titanium and Thorium as ammo types. The visual color of its bursts depends on the ammo: Titanium makes blue bursts and Thorium makes pink bursts. Because its projectiles are classified as lasers, Plastanium walls can block its blasts.

Fuse’s firing mechanics are unusual: a single ammo item produces a burst of three blasts, and the commonly quoted fire rate of 5.14 shots per second counts each individual laser in those bursts. Bursts per second are therefore roughly 5.14 / 3 ≈ 1.71, which corresponds to ammo consumption per second on Thorium. This makes Fuse relatively ammo-efficient compared with single-shot turrets that consume one item per projectile.

Key ammo and booster interactions and numbers:

• Titanium ammo: 66 damage, 4× ammo multiplier, +30% firing rate (effective per-laser fire rate increases from 5.14 → 6.68 shots/sec as reported), and pierce (laser). Titanium is notable because Fuse is the only turret that directly uses Titanium as ammo. Titanium is easy to supply if ore is available (no power required to produce).
• Thorium ammo: 105 damage, 5× ammo multiplier, and pierce (laser). Thorium deals higher raw DPS but is typically harder to supply because it requires power for production.
• Boosters: Fuse responds strongly to coolant boosters. Booster consumption is 18 units/sec. Water boosters grant 160% fire rate; Cryofluid boosters grant 235% fire rate. Cryofluid is straightforward to produce from Titanium and water, making a highly effective damage boost for Fuse when a Titanium supply is available.

Practical usage and strategy

• Position Fuse where enemy units are forced into tight groups or chokepoints so its three-blast bursts can pass through multiple targets in lines. Its unlimited pierce yields strong multi-target line damage if enemies are aligned.
• Fuse’s short range and spread make it ineffective against distant or fast outranging units (Daggers, Novas, Flares) and against many aerial units unless paired with an anti-air controller. Combining Fuse with a Parallax is effective because Parallax can pull flying units into range.
• Use Titanium when production simplicity or booster synergy (cryofluid) is a priority; use Thorium when maximum unboosted single-target damage per shot is desired. Boosting with Cryofluid massively increases DPS but typically requires a dedicated Titanium line in addition to water if Thorium is used for the turret’s ammo.
• Remember Plastanium walls block Fuse’s laser bursts; place Fuse where lines of fire are not obstructed by such walls or design wall placement with that interaction in mind.
• Fuse is inexpensive in terms of reachable materials and is fast to lay down in emergency defenses; its turret health is higher than average but usually secondary to proper placement and walling.

Numbers examples (from available stats):

• Unboosted theoretical DPS assuming each laser hits a target: Titanium burst DPS ≈ 441 DPS (66 × effective firing rate), Thorium burst DPS ≈ 539.7 DPS (105 × 5.14). Boosted with Cryofluid, DPS can more than double (examples in community data show very large gains when boosted). Use these figures only as guidelines because actual damage depends on how many of the three blasts hit at varying ranges.
