About

Play Elden Ring as Leon S. Kennedy, the way he plays in Resident Evil 4 (2005).

Leon is read from your own copy of Resident Evil 4 (the 2005 game, Steam's "Ultimate HD" release) every time the game starts: his model, textures, animations, voice, HUD and effects come straight from your RE4 install. Nothing from either game is in the download. Without Resident Evil 4, Elden Ring runs as normal and shows a notice.

Work-in-progress test build. Things will be rough in places; bug reports are welcome.

Start a new save as the Vagabond for the full experience. The mod is built around a fresh Vagabond character: Leon starts with both guns fully loaded and one green herb, and what he carries is saved per character from there. An existing character works too, but a new Vagabond is the way it's meant to be played.

What you get

Leon's own RE4 animations, played back as RE4 plays them: idle, walk, run, the quick 180 turn, the limping set at low health, falling and landing, climbing ledges, and ladders that climb themselves at RE4's pace.
RE4's over-the-shoulder camera and RE4's life gauge in place of Elden Ring's bars.
The handgun, the shotgun and the knife, with reloads, laser sight and RE4's own sounds. The knife parries a blow that lands as you slash.
Kicks: a stunned enemy gets the KICK prompt; the roundhouse sends everyone around Leon flying, a kneeling boss takes the leg kick.
QTE dodges: a DODGE prompt on every enemy attack (the backflip), and a dive to the side out of arrows and spells.
Green herbs: enemies that aren't bosses drop one half the time; carry up to three, each heals 30 %.
What Leon carries (herbs, both magazines) is saved per character.

Controls

Keyboard, with the pad's equivalents in brackets.

Ladders climb themselves once Leon is on them.
