Haven't encountered a virus or anything harmful with Kaspersky neither during the extraction, nor when running the game (and it scans background/child processes and etc., so...). It's most likely a false positive.
At any rate. You shouldn't bother. This Nightcrawler "game" is, true to it's title, quite literally, BAD. I mean, I rarely do this, but I insta-deleted it after finally completing (read: got that final one effing censored CG) it after wasting a good 25 minutes on it. In a mood now hence my being maybe overly critical, but... this is shit.
Lol.
Lol?
Good day, gents! (and ladies!)
