The WatchGuard Sourcebook is first product in a line of supplements centered around the WatchGuard universe, updated to be usable with the Mutants & Masterminds 3rd Edition ruleset.
The sourcebook is well laid out, matching the visual aesthetic that people have come to expect from M&M products, with vibrant colors and professional-grade character artwork. My only gripe would be the font choice for the body text as the letters feel crammed to tightly together, making it difficult to read for very long.
That said, the book goes into the Summit City setting, with a map, an at-a-glance section, and a fully detailed history. The history is pretty well thought out, taking time to introduce the various names and events that matter to the setting.
The real meat of this sourcebook however, comes from the character bios. Heroes and villains alike are statted out, with each one being given a full treatment discussing their History & Origins and Powers, and a full M&M 3e character sheet to go with it. The character vary in power level, but the average is about PL 10, which is reasonable for many M&M games.
Even if you’re not entirely sold on the WatchGuard setting, each of these characters can be pretty easily lifted and dropped into your own M&M Supers Campaign with very little need to change anything save maybe a few references to the WatchGuard setting in their Bios.
There’s a decent spread of character types, from Powered Armor to Metahumans, from magic to martial artists. There’s bound to be something here for anyone, and I feel that GMs who are looking for extra NPCs will get their money’s worth.
The last section of the book has several scenarios that GMs can run which are all set in the WatchGuard universe. These range from starter scenarios to ones intended for later in a campaign. The scenarios take place in the WatchGuard setting, but some creative substitution should be able to mangle them to suit any M&M campaign.
Overall the WatchGuard Sourcebook is a decent addition to an M&M 3e Gm’s arsenal. The character bios alone are helpful in populating a supers campaign, and the scenarios can also be useful for those days when you encounter GM writer’s block.
New GMs or GMs who don’t have the time to put together their own setting may find this product more useful, as it does a lot of world-building from the start, while leaving enough for new additions to be painless.
