Breach

Breach is a mid-range turret that fires piercing bullets and is intended as a primary defensive gun for established bases. It appears as a turret that accepts multiple ammo types — Beryllium, Tungsten and Carbide — and scales its role based on which ammo is loaded. Breach is unlocked after building the Core: Citadel and is commonly used to hold chokepoints, corners and the outer ring of base defenses where sustained, directional fire is required.

The turret’s nominal shooting radius is 23.75 tiles. When boosted with water it gets a large fire‑rate increase (water booster provides +250% fire rate), but continuous shooting with boosted fire rate consumes water rapidly; practical continuous boosted consumption is about 15 units of water per second to maintain the cooldown reduction. Breach is most effective when supported by walls and Mending (repair) coverage so incoming units are funneled and damaged over time.

Ammo defines Breach’s role:

• Beryllium: baseline ammunition with 63.75 damage, 2x pierce, and -70% building damage (so it deals 19.125 to buildings). It yields solid single-target DPS and consumes a moderate ammo rate when firing at normal speed.
• Tungsten: a higher‑pierce option with 71.25 damage, 4x pierce, +5 tiles range (total 28.75 tiles) and -70% building damage (buildings take 21.375). Tungsten shots pierce through armored ground units, allowing the Breach to threaten tanks and also hit vulnerable mechs behind them. Tungsten is shared with other piercing turrets and is a common defensive choice.
• Carbide: a heavy, high-risk/high-reward ammo with 325 damage, +7 tiles range (total 30.75 tiles), -70% building damage (buildings take 97.5) and it consumes 2 ammo per shot while applying an -80% modification to effective fire rate. Each Carbide shot splits into 3 frag bullets on detonation; those frags deal 227 damage, have 2x pierce, and themselves suffer -80% building damage. Carbide dramatically increases single-shot output and reach but reduces sustained shots due to its rate penalty and doubled ammo cost.

Practical notes and strategy:

• Breach is a reliable midgame gun that outperforms many simple turrets at stopping waves up to early tier‑3 enemies when using Beryllium or Tungsten. It loses relative value once higher-tier, more versatile turrets (for example generalist long‑range turrets) become available.
• Place Breaches at bends and narrow approaches so their piercing rounds can traverse multiple targets or hit high‑value units behind front liners. Pair them with walls (Beryllium Wall) and support structures like Diffuse and Radar for layered defense.
• Use Tungsten against mixed armor lines to punch through tank fronts and reach backline mechs. Use Carbide selectively for high‑value targets or chokepoints where the frag split can clear clustered enemies; plan for the higher ammo cost and reduced sustained rate.
• Breach is relatively expensive; prioritize resource income and mining reinforcement before building many. Combining several Breaches improves overlapping coverage, but for early game it is often more efficient to supplement with mobile units (Stell, Elude) or cheaper turrets.
• Historically, Breach was added during early updates and has had its ammo and description adjusted across builds; it remains the only multi‑ammo turret of its class on certain maps in earlier versions.
