The Fast Upgrades quest in Bloons TD 6, introduced in Update 40, presents a unique twist: at the end of each round, all towers are upgraded once for free along a selected upgrade path. This quest requires players to carefully manage tower paths and upgrades to optimize for the free boosts, making it both strategic and resource-efficient.
Key Strategies for Fast Upgrades:
- Upgrade Path Management: The game prioritizes the middle path for base towers unless another path has more upgrades, so choose paths thoughtfully. Before a round ends, invest in your preferred upgrade path to influence which direction the free upgrade will follow.
- High-Impact Towers: Start with versatile towers like Druids and Monkey Aces to make the most of early upgrades. For example, upgrading a Druid along the middle path to Druid of the Jungle provides efficient Bloon control and becomes a strong option for auto-upgrades as it scales with each round.
- Late-Game Adjustments: Towers like the Spike Factory can be invaluable for later rounds, especially when upgraded to paths like MOAB Shredder, as they provide strong support against tougher Bloons like DDTs and BADs in higher rounds. Aim for consistent upgrades to ensure critical support is in place by endgame.
Upon successful completion, the Fast Upgrades quest rewards players with Insta-Monkeys and cash bonuses, ideal for future challenges in Bloons TD 6.
