Larsen was a member of Gen Inc.
He was first and only seen during the first cutscene of the game in a security camera footage where another fellow member found him lying injured, however they were attacked by a Walker, the fellow member was killed by the Walker and it turns its attention to Larsen, he was presumably killed as the camera looses transmission and a mysterious man chuckles.
- It is possible that he might have been a Medic as he was wearing the same uniform that Parnevik was wearing.
- There are speculations that the unknown Norwegian radio operator was in fact Larsen as they share the same uniform and he would have been likely assimilated by the Walker that attacked him earlier.
- Coincidentally, the first victim of the Original Thing is named Henrik Larsen.
