Well, yes, but TMNB provides rules for security systems. If you're going to deliver burgers through a locked door, why not go all out and avoid motion detectors, pressure plates, tripwires and laser grids? You are ninja! What do security systems mean to you?

All that aside, the security system rules work pretty well. Each device has one or two skills listed that can defeat it, and many can be circumvented with gadgetry. For example, the aforementioned laser grid can be disabled with the right tools, or the ninja can choose to contort through the beam a la Catherine Zeta Jones in Entrapment. Or just use a mirror to redirect the beam.

TMNB also includes new enemies. There are soldiers, rent-a-cops and the like. But there are also new oni (the Pepper Oni and the Macker Oni), and the big bads of the book, the PARMs.

PARMs are Pets Affected by Radioactive Mutations, pizza-loving kung fu monsters that used to be household pets. (No prize if you guess the inspiration.) It seems the warlord Lo Cal has opened a pizza chain using all non-animal products in an effort to make people vegetarians. The Tai Cheese somehow mutates common animals into fighting machines. Now Lo Cal attacks Ninja Burger with Veal PARMs, Pork PARMs and even Eggplant PARMs (mutated house plants). And there are rules for allowing PARMs as Ninja Burger employees as well, though only secretly and as servants of Lo Cal.

Non-obstacle rules do come up. We get no new dishonor chart in this book, probably because it doesn't need one. There are modern-day weapons like pistols and submachine guns. The evil side of Wujenitsu gets explored, through the dark ninja magic that must only be used in direst circumstances. And there are the usual spate of bad jokes masquerading as house rules, including the Firefly Rule promised in the original Ninja Burger RPG book.

The first real surprise is that there's no Ninja Manager's section. At least, there's no point that says the employees must not read beyond it, like the first two books had. But there's still a sample delivery, to UnFood Corporation. Apparently the Ninja Masters have come to trust more in their employees' honor.

That delivery to UnFood is OK. It uses most of the security systems in the new rules, and the delivery targets are in hard-to-reach-stealthily places, as they should be. But it's also a little tedious. What amounts to a wandering monster table is included for whenever anyone is in the halls. It's a 1d6 table, and only the 1 is "nothing happens." Everything else slows down the game, with the possible exception of the janitor. Yes, it's fun to kill a security guard who wanders around the wrong corner. But it's not fun to find one every time you turn around.

But it's easy to ignore the random hallway encounters. Overall, this is a good addition to the Ninja Burger line. So long as the employees understand that a Pepper Oni with a flamethrower is nothing to sneeze at.
