About Lumenhold
Build towers, fight beside them, and protect the crystal — solo or online co-op with up to 4 heroes.
Pick one of four heroes and defend the glowing Lumen Crystal from waves of goblins, trolls, drakes and a magma colossus. Build towers, walls, traps and healing circles next to the monsters' path, then jump into the fight yourself. New to games? A short hands-on lesson starts the first time you play, and you can team up online with friends using a room code.
How to play
Monsters walk in through the gates and follow a path to the Lumen Crystal. Survive every wave to win. If the crystal breaks, you lose. Between waves there is build time: spend mana on defenses, then press Start Wave. Beating monsters gives more mana, and each defense also uses DU, your building space. If your hero is knocked out, you come back near the crystal in 6 seconds and your defenses keep fighting.
There are four maps, from Lantern Hall with 5 waves to Ember Throne with 10 waves and the Magma Colossus. Winning a map unlocks the next one. Each map has four levels: Easy, Normal, Hard and Nightmare.
On a computer, move with WASD, aim with the mouse and left click to attack. Q and E are special moves, 1 to 3 pick a defense, and U, R and X upgrade, repair or sell what you point at. On a phone, drag the left side to move, hold the attack button and tap the build buttons.

Tips and tricks
- Each hero builds different defenses. The Guardian builds walls and turrets, the Arcanist magic towers, the Ranger traps and the Mystic auras that heal, slow or shock.
- Build next to the glowing path. A Spiked Barricade on the path makes monsters stop and break it while your towers hit them.
- Ember Drakes fly over walls and traps. Shooting towers can hit them, but the Whirl Blade and Shock Aura cannot. Kill Powder Imps early, because they explode on defenses.
- Stone Trolls smash defenses for double damage. Repair hurt defenses between waves, and repair traps to refill their uses.
- Changed your mind? Before the wave starts, Undo takes back your last defense for a full refund.
What makes it fun
Lumenhold mixes tower defense with an action game. You are not just placing towers and watching; you run in, fight beside them and save the crystal yourself. Gold from battles buys lasting upgrades like Weapon and Defense Power, and your first win each day doubles the gold.
