Massivization allows nails to pop 8 Bloons at once, including frozen. Also increases Foam and Sentry effectiveness.
~ BTD6 description

Oversize Nails is the 1st upgrade of Path 3 for the Engineer Monkey in Bloons TD 6. It corresponds to the 9-Inch Nails upgrade from the BTD5 generation. It increases the pierce of the main Engineer's nailgun nails from 3 to 8, and allows them to pop Frozen Bloons. Unlike BTD5, this upgrade now also affects Sentry Guns, which now gives the Engineer's sentries +1 pierce and the Shatter damage type (which pops frozen). It also increases Cleansing Foam pierce by +5.

It costs $380 on Easy, $450 on Medium, $485 on Hard, and $540 on Impoppable.

Strategy[]

Summary[]

Oversize Nails improves overall pierce for the Engineer Monkey and allows the Engineer and his sentries to pop Frozen Bloons. This is most useful with countering grouped bloons, more specifically in the early-game, or to improve sentry performance later on.

Tips[]

  • It makes useful early-game pierce akin to a Spike-O-Pult with greater attack speed but with significantly less pierce.
  • When further upgraded along Path 3, particularly with Double Gun, it is quite reliable at stalling early-game bloons.
    • This makes it the best early game Engineer Monkey.
  • Oversize Nails is one of the few sharp projectile towers that can pair well with Ice Shards for the activation of multiple ice shards.

Version History[]

Engineer crosspathing had previously been almost completely useless, but in later updates this upgrade among other upgrades have received crosspathing benefits in later updates.

20.0
Continuing our efforts to make crosspaths meaningful and fit the style of each path more solidly, a number of crosspath and base level balance shifts were made.

  • Buff Oversize Nails now adds +1 pierce to all sentries deployed by the Engineer and allows them to pop Frozen bloons.
21.0
Engineer is quite poor in terms of crosspathing, so we've added crosspath benefits to Cleansing Foam as well as an overall price buff to the middle crosspathing upgrades. [...]
