Each of the available Mercenaries will only get “unlocked” in the right age, so as to avoid the possibility of these troops becoming too strong by debuting an age too early. For instance, you wouldn’t want to see other players controlling Hessian Cavalry, because that’s going to make them way too dominant in the present age. Still, you shouldn’t fret, as some Mercenaries will still be effective in a way a few ages after they debut, mainly when attacking areas that aren’t protected anymore.
Resource management is still very, very important when you’re dealing with Mercenaries. Each of the 15 or so types has their own requirements, and higher-end units, of course, will require more resources.
Take this quick example, for instance. If your Basic Soldiers are Hittite Warriors, then the mercenary Hun Warriors are improved versions. This actually may not qualify as a tip, but it’s something that’s nice to know as you send your best troops forward.
Here’s one last thing you should remember about Mercenaries – they won’t return to your camp once the battle is done, even if all defensive buildings have been destroyed. That would make it a better idea to send them only when doing medal attacks.
