This pamphlet takes aim at dealing with the "problem" of having FIST agents that have survived too much. There are 2 paths provided to achieving OLD DOG status - enough advancements, or fulfilling milestone achievements based on their role, which is the main rules innovation here. From there, we're presented with branching options for our OLD DOGS: retirement has 3 end-points, and there's an open-ended option by pointing at high-level play with ARM (which feels like a solid mix of RED and Suicide Squad, a great combo). There are some rules of thumb for ARM Unit play, including a specops team of CROs that specialize in neutralizing OLD DOGS.
Overall, it's a solid set of ideas, and has good enough bones and momentum to hopefully be iterated on and fleshed out even more.
