Hello everybody. I have some great news!
I have purchased issue #113 of Super Play (Swedish gaming magazine), which contains a review of killer7 (and possibly more content) and it should arrive in 3 days or less. When I get the opportunity to, I will absolutely make sure to scan all of the pages related to killer7.
Due to the current circumstances, I unfortunately cannot scan every single page. However, when I do get the chance to, I will scan all of them and upload them on either https://segaretro.org or https://archive.org.
The pages are all in Swedish, but I will provide a translation.
Thank you.
