Character Summary: Siegfried Alpenbrecht

Siegfried Alpenbrecht was once a respected therapist and a childhood friend of the professor, the game's antagonist. After a tragic event left the professor isolated and mentally unstable, Siegfried stayed by his side, offering support and therapy deep within the remote manor. However, what was meant to heal ultimately made him a target. Early on, the darker side of the professor viewed Siegfried as a threat — and subjected him to a horrific transformation.

When the player encounters Siegfried, he is no longer recognizable as human. His towering, bulky frame is stitched together with metal implants, raw open wounds, and dangling electrical cables. His mind has been shattered beyond repair: chemical experiments destroyed his higher reasoning, leaving only a chaotic, broken shell.

Siegfried’s behavior is terrifyingly unpredictable. He can shift from eerie, childlike humming to violent, destructive rages without warning. Sometimes he bursts into uncontrollable laughter, only to fall silent a second later — or charge blindly at the player. Despite his monstrous form and danger, there is a tragic weight to Siegfried's existence. Players are meant to feel both fear and pity when encountering him — a terrifying reminder of what the professor’s descent into madness has cost.

• Shifts randomly between childlike joy, eerie calmness, violent destruction, and manic rage.

• His laughter and humming should feel unsettling, as if emotion is misfiring inside a broken mind.

• No real speech is possible, but the player may hear him struggle to form words, creating moments of raw sadness beneath the horror.

• Must be portrayed not only as a threat, but also as a tragic figure — a victim whose humanity has been stripped away.

• Perform a range of wordless sounds: manic laughter, failed attempts at speaking (broken syllables), bellowing roars, soft humming.

• Emotional whiplash is key: sudden, jarring transitions from calm to violent should feel unsettling, not cartoonish.

• Convey the feeling that deep inside, some remnant of humanity wants to communicate — but is trapped and broken.
