Three heroes. One deck. A world in eclipse.
BTR ECLIPS is a tactical roguelike deckbuilder where elements collide. Pick three heroes, shuffle their powers into one shared deck and fight across five lanes beneath a dying sun — where the right two cards, played in the right order, can bring down a giant.
Every pair of elements has its own reaction
Each hero commands an element: fire, ice, lightning, darkness, telekinesis, portals or time. Mark an enemy with one, strike it with another, and both traces detonate. Portal meets fire:
Rift Inferno. Ice meets lightning:
Superconduct. There are 21 reactions, one for every pairing, and their power grows with the traces you stack, not with the card you play.
Read the battlefield. Break the plan.
Enemies reveal their intentions before they strike. Five lanes turn every turn into a positioning puzzle: front-line enemies shield the ones behind them from single-target attacks, lane attacks sweep the whole lane, and a well-placed shove pushes a threat into another lane. Spend your Ember wisely, then fill a hero's Ring to draw their
Eclipse card — a devastating ultimate unique to each hero.
Build a party worth fighting for
Start with four heroes and rescue three more as you push deeper into the eclipse. Every trio changes your deck, your reactions and your options. Reactions earn Essence: spend it at the Fusion Altar to forge
Combo cards, 21 duo cards born from the bond between two heroes.
Find your route through the eclipse
Cross four acts, from ruined sanctuaries to the Crown Engine. Choose your path through battles, elites, rest sites, shops, treasure and unknown events, and collect sigils that bend the rules of your run. Raise the Curse for harder fights and richer rewards, or take on the Daily Eclipse.
Bring the giants down
Ten bosses wait across the acts, each with its own attacks and shifting battle patterns — and something older waits for those who dare to look for it. Land the final blow and watch the eclipse shatter as dawn breaks over the battlefield.
