About Echo Arena
What's inside the next pack?
Settle into your own retro collection room. Pick up a pack, tear it open, and turn over each card yourself. Keep your new discoveries, turn duplicates into coins, and look for the next empty space on your collection wall.
100 designs. 10 visual variants.
Discover different versions of each design, from a simple printed finish to glass, laser and cosmic effects. Special card surfaces change with time or your viewing angle. Together, 100 designs and 10 variants make up 1,000 collectible card numbers.
Build your collection, one slot at a time
Walk up to the display frames and place each card into its numbered slot. As the gaps disappear, your room becomes a personal gallery. Open a close-up view whenever you want to take a better look at a card.
Turn your collection into progress
Filed cards add to your collection value. Visit the retro computer on your desk to unlock more cards per pack, better odds for rare variants, and higher duplicate returns. Progress also unlocks click-to-open packs, hover-to-flip cards, and automatic card reveals.
Put duplicates toward the cards you're missing
Duplicate cards automatically become in-game coins. Unlock ordering, spend those coins on specific card numbers you do not own, and add the missing pieces to your wall.
- Pick up unlimited in-game packs and enjoy hands-on opening and reveals.
- Collect 100 designs in 10 variants, for a total of 1,000 card numbers.
- Fill display frames across four walls and inspect cards up close.
- Unlock 25 upgrades to improve your pack-opening and collecting experience.
- Use three independent save slots and choose from ten interface languages.
