Old skool security

Commonly this exists in a form of a laser grid, or some other grid of dangerous or outright fatal things that "fail" in a pattern (regardless if this failing is intentional or not). The grid can be in motion, require acrobatics and so forth. Also includes many things that exist as in-built traps.

Mostly of interest in games that presumably should've outgrown these.

Also, the old skool refers to old video games, not real security systems.
