SEVEN INTO HELL

[celso junior]

Dear all,

I have been looking for ages a war movie, a bad one of course, and the reference I have is the title SEVEN INTO HELL.
I also believe that it is from the later 70's or at least early 80's. I already done a search on Amazon, IMDB and nothing.
I'm sure that the film exist because i rent it 15 years ago and I found a image of the video cover in a site. The sinopsis is similar to (GI BRO/INGLORIOUS BASTARDS): a group of mercenaries killed by mistake some americans soldiers pretending be a SS group, after that they must replace them in the mission. Now start the sci-fiction session, the group must destroy a place where the nazy are doing some biological weapons.
If somebody knows it, or perhaps knows a different title, could be very kind to share that info with me.

Thank you in advance
