Written on the official rulebook July 31, 2026

Six years of work, an already sold-out fair preorder, a number one spot in BGG's Hotness. I read the twenty-four pages of the rulebook because what makes this game different is not what is being said around.

Five categories: who made it, how new it is, what the box is worth, how well-crafted it is, how self-explanatory it is.

FrogScore 8.5 / 10
SignatureBehind it are Great Western Trail and Maracaibo. Young, less historical publisher. 9.5
OriginalityExplorers don't go back and the map grows: known ideas, new combination. 8.5

Each entry also explains why it's not higher, and the evidence is in the piece below. The FrogScore only includes what no one would want in smaller doses: weight, randomness, and interaction are left out; you'll find them in the profile.

Buy it if you like to decide when to stop, and want a medium-high weight with very little downtime
Leave it if you can't stand a draw changing your round, or you're looking for campaign and cooperative play
Window no Italian edition announced, other languages planned only after the first wave

The map doesn't empty, it grows

It's worker placement, with a rule that reverses the usual: explorers don't go back. You place them on an action space and they stay there until the end, and that space is lost to everyone — including you.

But meanwhile, Antarctica expands: each discovered landscape brings spaces that weren't there before, and the station you build becomes explored territory with an action open to others as well. You expand and in the same gesture give something away — this also happens on your table, because the tiles are added in a line and the space needed at the end is not the same as at the beginning.

The core

You draw cards from your deck one at a time and each time you choose: you play it and move forward, or you stop and the round is what you have. Storms pay you in energy on a rising scale — two, five, eleven — but they shut down everything else: with two on the table, expedition cards give reduced bonuses, with three they give nothing, and each one covers a base that was giving you coins or stations.

It doesn't matter what you drew. It matters when you stopped.

Doubt It asks you to tighten, then punishes you if you doTo power up a station, you need surrounding presence, so the game pushes you to cluster. Then, at the final count, it takes three points for each powered-up station next to another of your powered-up stations. On paper, it's an elegant tension; I suspect it's also the point where players make the most mistakes at the table, and resolving it requires plays, not pages.
This is the only serious doubt the reading left us with. Everything else can be found below. See the sheet →

The round, in three phases

IPreparationDraw as much as you want. All together. IIPlanningTwo explorers and one card chosen from five. All together. IIIActionOne action each, clockwise, until everyone passes.

Two out of three phases are played simultaneously, and in the third, you do one thing at a time. This is why, even with four players, you are never left waiting.

Two designers, not one

Alexander PfisterGreat Western Trail, Mombasa, Maracaibo, Boonlake. The engine that grows in your hands and the moment you have to decide whether to push further: it's been his obsession for ten years. Peter PrinzThebes, 2007: excavations, expeditions, time as a scarce resource. Brings the DNA of exploration, and it's the part that is most felt here.

“It's a new Pfister, true. But also honor Peter's work.”

Nanox Games, on the BGG forum

The third signature is Martin Mottet, illustrations and graphics together: in the rulebook almost every effect goes through an icon, and that's why the game remains readable even without an Italian edition. In six years, the setting has changed several times, finally settling on an alternative history with a meteorite in Antarctica — no aliens, no monsters, and no sled dogs getting hurt: Pfister himself confirmed it to those who asked.

Why it costs what it costs

240cards 140wooden pieces 20punchboards

Punchboards and cards are about double the norm in this range, and recycled wood instead of plastic doesn't help the price: according to the publisher, it will never go below sixty. In return, the six meteorites each change the setup and the central action of the map, and that's where the variety ended up instead of a campaign.

Solo, against Arka

Arka has its own board, its own stations, and a deck of action cards: you flip one per turn and execute it from top to bottom, while an explorer moves on a rondel and activates everything it passes. The detail that makes the solo game faithful is another — when it occupies an action space, Arka does not execute its effect. It just blocks it, exactly as a flesh-and-blood opponent would.

Standard1-2 extra cards Legendary3-4 extra cards Epicall five

One thing to know beforehand, however: Arka does not do the preparation phase. It doesn't draw, it doesn't risk storms, it never decides when to stop. It contests the board without experiencing the dilemma that is the heart of the game.
