Energy to Power Towers

A tower defense game. Roll a card. Build the deck. Hold the lane. Six players per server, one base each, 100 HP. Xenos come down your lane in 5-wave Stages, and they do not stop. Everything between them and your core is whatever the gacha gave you. RNG decides which units you get, never what they do once they're down. Downed Xenos drop Energy. Carry it to your core for upgrades that last the Stage. Your core makes Energy too. A higher core carries more, runs faster and fields rarer units. Sprint on Stamina; the Treadmill grows it. - Clear Stages and beat bosses for Tickets, then roll Basic, Super or Ultra. Six rarities, Common up to Secret. Full odds in-game. - Up to five deck slots: two at the start, unlock more with your Endless record. Deciding who sits out is half the game. - Fuse duplicates into stars: 4 copies for 2★, 6 for 3★, plus gems. Stars are permanent. Farm for coins or push Endless up the leaderboard. Trade cards, join a squad, clear daily quests.
