MÉSOWORLDS BEFORE US
THE PLAYER JOURNAL

Your first
expedition.

A guide to opening boosters, understanding rarities and joining auctions. The same rules apply in French and English.

01 / BOOSTERS

Five cards, at your own pace.

Every booster contains five independent draws. Origins and Echoes of the Past share two free daily openings, renewed at midnight UTC. Extra openings cost 60 Ambrons, after confirmation.

Cards and the opening receipt are saved when you open the pack. Reload after two cards and you return to the same pack, with no new draw.

02 / RARITIES

Three ways to discover a creature.

  • ◆ Common75%
  • ✦ Rare22%
  • ✧ Secret3%

These provisional beta odds apply to each card. No rare is guaranteed, and duplicates are possible. Some secret cards feature fossils.

03 / COLLECTION

One album, several finishes.

A common, a rare and a secret complete a creature. Tap a card to enlarge it and examine the details. Extra copies are duplicates; they do not increase the number of different cards in your album.

04 / AUCTIONS

Ambrons move between players.

The seller reserves a copy. A bid reserves the buyer’s Ambrons; a higher bid releases the previous bidder’s reserve. At closing, the winner gets the card and the seller gets the final price.

The MÉSO shop also offers cards at fixed prices. Auctions and the shop use the game’s virtual currency. No real-money payments are enabled in this beta.

Your next discovery is waiting.
