Some women are seen in skimpy 60's clothing.

A few people get strangled/electrocuted by the monsters. They are usually seen burnt, torn up, and/or a bit bloody afterwards.

One guy gets electrocuted by a power box.

Another guy falls off a railing. We don't see the actual impact, but seconds later he's seen in a pool of blood.

Some of the monsters get shot by the lasers (they ooze green blood), and 2 others get stabbed in the eye(s) with guns.

4 or 5 uses of "damn" or "dammit", and one use of "bitch", which is used as a term for complaining, not against women.

Nothing.

The monsters, despite being cheap-looking, are actually pretty creepy and make spooky sounds.

The occasional violence make catch a few viewers off guard.
