Short but sweet. BOO offers a lot in a small package. Leaning hard into monsters and magic it offers an alternative framework for FIST games plus plenty of options worth adopting. After all, how can you have a bionic secret-agent without a sasquatch to fight?
The idea of budget cuts as a persistent problem during mission generation is one every GM should consider, especially if their PCs have botched their last few missions. My PDF also had a blank page nine that should be trimmed, but that's a minor blight on this small but brilliant gem.
