Icecrown Onslaught
Northrend Onslaught in full 3D, with the game's own models. Take Jaina, Saurfang, Sylvanas or Gul'dan onto a frozen Icecrown arena, cut through ten waves of the Scourge, then face the Lich King and Frostmourne.
Jaina Proudmoore
Glass-cannon caster — freeze, blink, and burst from range
“An exile of the Kirin Tor who wed forbidden frost to fire. Cold hands, colder heart.”
10 escalating waves, then the Lich King himself.
Four heroes, twelve spells
Jaina freezes and blinks, Saurfang charges in and whirlwinds, Sylvanas kites with a wolf, traps and a backflip, and Gul'dan drains life while his Felguard holds the line.
Bosses, loot, then the King
Ten waves of the Scourge, with Lord Marrowgar, Lady Deathwhisper and Blood-Queen Lana'thel along the way. Loot boxes give stacking powerups, and each boss drops real Icecrown Citadel trinkets, rings and necks. Then the Lich King arrives with frost orbs, Death and Decay and raised dead.
How to play
WASD to move, mouse to aim, left-click to attack, and Q / E / R (or Space) for your spells. On a phone, turn it sideways and use the twin thumb-sticks. The 3D arena needs WebGL and loads about 9 MB of models on the first run.
