The Prussians are headed to your tabletops in Black Powder Epic Battles. And just like at Waterloo, you still have a little bit to wait. But they'll get here. In the meantime, check out the rules for these new figures in this preview.
From the website:
On the Epic Battles tabletop, your Landwehr regiments will augment the regular line infantry, forming the classic ‘mixed’ Prussian brigades. Slightly cheaper than Musketeers and Fusiliers, they do suffer from the Unreliable special rule but are in all other respects thoroughly acceptable frontline units. When well led, they’ll do their commanders proud, and their burning hatred of the French gives them the Tough Fighters rule, meaning they can re-roll a single failed dice roll in hand-to-hand combat in each round of fighting. While taking a run at the Imperial Guard might not be the best idea in the world, your plucky militiamen are certainly no slouch with the bayonet!
Similarly your cavalry, while also unreliable, are capable and numerous, and determined to get stuck into the French with their lances. Finally, the Jägers have the Reliable and Elite 5+ rules (enabling recovery from disorder) and are crack shots with their rifles. Scatter a few companies throughout your army and watch with pride as they empty saddles and harass enemy officers.
