Legends Under Fire

Play the Kingdom Under Fire: The Crusaders campaign with a league of legends champ kit.

When a battle loads, a champion select opens over the game. Pick Ahri, Garen, Darius, Malphite, Amumu, Annie, Brand, Lux, Morgana or Miss Fortune and fight the mission with that champion's abilities on 1 / 2 / 3 / 4 (their Q / W / E / R). Names, icons, cooldowns, mana costs and damage come from your own League of Legends install, each kit is tuned for KUF's big battles (Garen spins, Miss Fortune's Bullet Time fires wave after wave, Amumu's curse stuns the crowd around him), and KUF plays them with its own spell effects. Your hero becomes the KUF hero that suits the champion (Garen and Darius fight as Gerald, Miss Fortune and Lux as Kendal, Malphite, Amumu and Brand as Regnier, Morgana, Ahri and Annie as Lucretia) and still commands the army.

Controls in battle

• 1 2 3 4: champion abilities (Q W E R). F7: change champion.
• WASD: move and strafe. Mouse: KUF's cursor and attacks.
• Mouse wheel: turn the camera (down = left, up = right).
• Arrow keys: KUF's spell ring (Up/Down open, Left/Right choose, Enter use).
• 5 6 7 8: select troops 1-4 (moved from 1-4 so those cast abilities).
• H: keyboard legend with every key, shown for a few seconds at the start of each battle.

What you get

• Ten champions, each with a hand-tuned four-ability kit built on its real League data.
• Champion level follows your KUF hero level (up to 18): abilities rank up, the ultimate unlocks at 6.
• A League-style ability bar with cooldowns, rank pips and mana.
• Hits go through KUF's own damage: kills count for your troop, stuns and knock-ups knock soldiers down, slows chill.

Requirements

• Kingdom Under Fire: The Crusaders (Steam). The mod checks for the Steam build and stays inactive on any other.
• League of Legends installed (only its files are read; League is never started or changed). Single player.

Notes

• The hero swap applies from the next battle after you pick a champion. Your save itself is not changed.
• Log: %LOCALAPPDATA%\KufLegends\kuflegends.log. The mod writes the troop keys (5-8) into Documents\KUF2 Crusader\KUFC.ini; the original is backed up once as KUFC.ini.kuflegends-backup.
