Description

A pursuit vehicle built for stealth

Ultra Agents ran through 2014 as LEGO's spy-versus-villain theme, pitting secret agents against the criminal organisation Antimatter. Tremor Track Infiltration fits that brief with a compact pursuit vehicle rather than a sprawling base set. At 241 pieces spread across 86 distinct part types, the build offers a reasonable amount of variety for its size, making it a manageable afternoon project rather than a multi-day undertaking. It sits comfortably among the theme's smaller vehicle sets. Ultra Agents skewed toward older builders looking for a bit more detail than entry-level sets typically offer, and this model reflects that with its compact but busy silhouette.

A muted, tactical colour scheme

The dominant colours are black, dark bluish grey and light bluish grey, with dark tan used for accents. That combination reads as deliberately understated compared with brighter Ultra Agents sets from the same wave, reinforcing the infiltration angle in the set's name. If you're after grey- and black-toned parts for your own builds, or want to match an existing Ultra Agents fleet, the parts list on this page breaks down exactly which pieces come in which colour. Compared with brighter Ultra Agents releases built around blue and orange, this set reads as noticeably more restrained.

Two minifigures, one confrontation

Two minifigures come with the set, in keeping with the agent-versus-adversary pairing typical of Ultra Agents releases. We stick to what the catalogue data confirms rather than guessing at specific character identities or accessories, since those details vary by listing. For collectors building out the wider Ultra Agents range, this set sits between the smaller gadget packs and the larger headquarters builds in terms of scale. That restraint also makes the set a reasonable display piece on its own, regardless of which specific roles the two figures play in the wider story.

Using the parts list beyond this set

With 86 unique part types packed into 241 pieces, Tremor Track Infiltration is a reasonable source of grey and black elements for custom builds, not just a self-contained kit. The full parts list on this page lets you check colours, shapes and quantities before buying, trading, or hunting for specific pieces to complete another project in a similar palette. Since the set dates from 2014, checking the parts list is also worthwhile for anyone after older moulds or colour variants that have become harder to find since.
