About this game

No ads. Ever. Just merge, defend and outplay.

Starvoxel: Defender is a merge tower defense strategy game with real-time PvP, online co-op and a 100-level boss Dungeon. Build an 8-card deck, drop defenders onto your 3x3 board and merge matching cards to level them up. Every round is a fresh tactical puzzle: spend your gold, place, merge and hold your lane.

MERGE FOR POWER
Drag a card onto an identical defender to merge them. One star becomes two, two become three, and damage doubles at every step. Plan your board, refresh or freeze your hand and choose the perfect moment to merge.

FACE GIANT BOSSES
The Dungeon has 100 levels across 10 depths, and every level ends with a boss. Break shields hit by hit, push through phase gates and survive summons, freezes and enrage. Every 10th level a guardian boss waits, all the way down to the Abyss King.

REAL-TIME PVP ARENA
Duel other players 1v1. You defend your lane, they defend theirs, and you both prepare at the same time. Win trophies, rise from Stone to Champion and claim 40 rewards on the trophy road. If no opponent is found within seconds, you face an AI opponent that is clearly labelled.

DEFEND TOGETHER IN CO-OP
Invite a friend or get matched with a partner for co-op tower defense: two lanes, one shared core. Clear 5 co-op arenas with 5 runs each, climb from Rookie to Nightmare difficulty and unlock Endless.

COLLECT AND EVOLVE
Collect 30 defenders, each with its own ability. Level up your cards, open packs and choose one of three evolutions for every defender. It activates when that defender reaches three stars.

FEATURES
• Merge tower defense on a 3x3 board
• 8-card decks you can save and share
