Faster Production returns as the 1st upgrade of Path 2 for the Spike Factory in BTD6. It allows the Spike Factory to produce spike piles +25% faster (x0.8 attack cooldown), for a rate of one spike pile every 1.4s by default.
It costs $510 on Easy, $600 on Medium, $650 on Hard, and $720 on Impoppable.
Upon upgrading to Faster Production or crosspathing with Faster Production (except for Tier 5 upgrades), the Spike Factory will gain two storage depots on both sides. All Spike Factories with Faster Production, except Spiked Mines and Tier 5 upgrades, will also turn the factory's feet purple.
Faster Production improves the Spike Factory's production of spikes. While less efficient than multiple base Spike Factories, Faster Production is quite valuable in combination with higher level upgrades.
Faster Production is generally better for crosspathing both the top and bottom paths high tier upgrades.
If using a low tier Spike Factory, try only buying this upgrade after Bigger Stacks has been bought, or if planning going for Long Life Spikes or above, especially Perma-Spike. Otherwise, a 0-1-0 Spike Factory is a lot less cost-efficient than going for multiple base Spike Factories.
Crosspathing with Path 2 has been softened, leading to Faster Production getting indirectly nerfed in the process.
Base projectile lifespan reduced from 70s to 50s.
Faster Production price reduced ($700 → $600).
Spike Factory attack speed bonus decreased (0.6x → 0.8x, or +66% → +25%), for less attack speed (1.32s → 1.4s).
