Y8 Strategy Tips

Progression hinges on timing. Unlock new slots early; they give you the freedom to layer multiple turret types without crowding the map. Prioritize research that boosts incremental income—every extra coin compounds over the next wave. Mix high‑damage lasers with slow‑fire artillery to cover both burst and sustained threats. Remember, idle earnings keep flowing even when you’re not actively clicking, so set up production chains that generate resources while you’re offline. Upgrade the base’s armor after you’ve secured a solid turret grid; a stronger hull buys you the breathing room needed for expensive tech upgrades. Keep an eye on the enemy composition; some waves favor speed, others favor armor. Swapping a turret’s focus on the fly can turn a near‑loss into a triumphant defense.
