Field Guide to Suldan is a fan made expansion to GOTY Lancer. Of course, "fan-made" is an unfair description for a 250 page book with gorgeous artwork and full COMPCON integration. This would easily be a $30 sourcebook if it were for D&D 5e.

Suldan introduces a planet where prior Union efforts comprehensively failed, with the previous Administrator teaming up the planetary despot. There was a coup, and the world is now wracked by rebellions and private corporate armies while under partial blockade from the faltering planetary defense grid. This is the kind of place where a small team of skilled mech pilots can make a difference. Suldan is a mishmash of gamable ideas, with a cultural heritage of mech dueling and gladiatorial combat to add to the fun. While this book does have a campaign included, there are lots of example situations that build towards a final confrontation for the fate of Suldan. But at the end of the day, Lancer is a tactical game, and I think there's a market for a book of encounters with excellent maps.

Players have an entirely new line of mechs to enjoy from Chandrasekhar & Herschel. C&H is a little less tightly themed than the other companies, and none of the frames really grabbed me. The good news is that it means that there's nothing obviously broken in there, munchkin that I am. Suldan extends the base game with new variant licenses, which give bonus systems and weapons not associated with a specific frame if you've bought far enough into one mech manufacturer. There's also a cool rock-paper-scissors dueling substem, as well as a number of interesting enemy mechs that do fill in gaps in the base game.
