Larger Service Area (BTD6)

"Shoots further and deploys sentries in a much larger area. Sentries have longer range"

- In-game description

Larger Service Area is the 1st upgrade of Path 2 for the Engineer Monkey in Bloons TD 6. It increases the range of the Engineer from 40 to 60. In addition, sentries spawned by this Engineer gain +4 range, and newly placed Bloon Traps with this upgrade can be repositioned to any valid location within range.

It costs $210 on Easy, $250 on Medium, $270 on Hard, and $300 on Impoppable.

Summary
Larger Service Area is a lot more useful in this game compared to BTD5, as it is now far cheaper, is a Tier 1 upgrade rather than Tier 2, and the Engineer's sentry spawning algorithm is now smarter. The extra range bonus from Larger Service Area is still massive for its cost, making it have the greatest valuable in combination with upgrades specifically targeted at improving the Engineer himself rather than his sentries.

Tips

 * This upgrade is hardly useful for sentries, due to slightly interrupting the spawning algorithm of the sentries, but it is still kind of useful for the main Engineer.
 * Pairing the Larger Service Area upgrade with Double Gun allows the Engineer to reach further, allowing the fast pinning attacks to reach considerably further, although this misses out on the Sentry Gun upgrade.
 * Generally speaking, this upgrade is usually not very necessary unless it's to improve coverage for the Engineer's nailgun. Even in BTD6, this upgrade doesn't do very well in combination with sentries.
 * The order of purchasing Larger Service Area matters for sentries. If Larger Service Area is bought before the Sentry Gun upgrade, all sentries from will be spawned further. Conversely, buying the Sentry Gun upgrade first before getting Larger Service Area will keep sentries within the same location.

Trivia

 * Larger Service Area costed $100 less than its BTD5 counterpart on initial release, but now that this upgrade became $250 as of Version 21.0, purchasing this upgrade alone became around 55% cheaper than it did in BTD5.
 * A "service area" in the context of mechanical engineering likely refers to the space at which mechanic work can be operated, which makes sense considering that the Engineer Monkey is mostly a mechanical engineer.
