This video nastie was eventually released in Britain with 2 seconds cut. Those two seconds must have had all of the action because there was really nothing left in this movie that would qualify it as a nasty.

Some Vietnam soldiers are trapped in a cage and they get an opportunity to gnaw on some flesh. That is the only nudity you see in the film - 2 seconds. One of them bites his Captain's (John Saxon) arm when being rescued and he has the dormant virus that will come to haunt him in later years.

For some reason, the two soldiers never fully recover and they go on a rampage that is tame by cannibal standards. The police end up chasing them all in a sewer, but our hero escapes and puts on his uniform for an honorable death.

You can be sure they did not get them all, but I don't know if there was an Apocalypse II.
