Quick answer

Choose Too Many Bones: Undertow if you want a self-contained entry point with a smaller footprint and new Gearlocs to learn. Choose the Too Many Bones base game if you want the fullest roster of Gearlocs and the widest variety of encounters from the start.

What “standalone expansion” actually means for Undertow

Undertow is sold as a standalone expansion, so you do not need the base game to play it. That makes it a legitimate first purchase rather than an add-on you shelve until you own the original. The trade-off is that it is not a content expansion for the base game in the usual sense; it is its own box with its own Gearlocs and its own reason to exist.

If your group already owns the base game, Undertow still works as a second box, but its main value is variety and portability, not a campaign continuation. If you are starting fresh, the standalone nature means you can pick Undertow without worrying about a missing core set.

Scope and table time: smaller box, tighter session

The base game is the larger commitment in terms of content and setup. Undertow trims that down, which is the main reason to pick it as a first box. A tighter scope usually means faster teach and faster teardown, but it also means fewer combinations to explore before you start to see repetition.

That is the central trade-off: Undertow is easier to get to the table, while the base game gives you more long-term discovery. Neither is wrong; it depends on how often you actually play.

The Gearloc question: new faces vs the full roster

Undertow brings its own Gearlocs, including Duster, whose journal frames the story. If you are drawn to specific characters, check which box contains them before you buy. The base game holds the original Gearloc lineup, so choosing Undertow first means you may still want the base game later for the characters you skipped.

For solo players, fewer Gearlocs can be a feature: you learn each one deeply instead of spreading thin. For groups that rotate characters, the base game’s larger roster is the practical pick.

Trade-offs to weigh before you buy

  • Entry cost and commitment: Undertow is the lower-commitment first purchase because it stands alone; the base game asks for more shelf space and more setup time but returns more content. If you are unsure the game will hit the table often, start with Undertow.
  • Gearloc variety: Undertow gives you its own Gearlocs, while the base game gives you the original lineup. Pick based on which characters you actually want to play, not on box size. Check the Gearloc list for each box before deciding.
  • Long-term replay: The base game offers more combinations to explore over many sessions; Undertow’s tighter scope means you may see its edges sooner. Neither box is a dead end, but the base game stretches further before you feel the need to expand. Plan to add the other box later if you catch the collecting bug.
