Upgrading them will have a big impact on the power of your army. Your main-line infantry units, 'grunts', are your most common unit. Be sure to invest in getting one or two heroes to maximum level as quickly as possible. In some cases you may only summon one or two. Typically a scenario won't provide a chance to summon all your heroes. A powerful way to employ this ability is to attack on one front and then get back to counter-attack an enemy army that threatens one of your territories. This makes the player's army very versatile. Many players overlook the fact the ability to move into a controlled territory before attacking. Tip #5: Don't forget the move-then-attack option. These provide no meaningful defense and raise the cost of other districts in the city. Never build military districts in the middle or back of your area if you can help it. Ideally you want to build as few military districts as you can get away with, placing them only as needed to prevent an enemy army from taking your territory. Place military districts on the outside of your territory if an enemy army is threatening. They are extremely powerful and building several of them should be your primary goal. Palace districts provide reoccurring income of all major resources. Tip #3: Palace districts are even MORE important. The more you make, the more you'll be able to build up. From there you should attempt to build as many merchant districts as you can get away with.

Your first district should always be a merchant district. The sooner you build merchant districts the more wealth you'll produce over the course of the game. You need wealth from cities to build more districts. To fully eliminate such an army you need to capture their capital territory. In the Alin campaign you can defeat these armies directly, but in the Vinci and Cuotl campaigns an army defeated in the field will regroup. Defeating them in the field only drives them back. They attack your territories and reinforce scenarios making them harder. Enemy armies are the real threat on the strategic map. On the other hand be careful not to miss important side-quests that may provide extra experience awards for your heroes. Finishing a quest can often trigger events or other quests that you may not be prepared for, particularly on a higher difficulty setting. Control the flow of a scenario by not completing quests until you are ready for whatever might come next. Attacking them prematurely can result in the enemy's larger forces wiping out your army.

In many scenarios the enemy has vast forced already prepared. Take advantage of opportunities to build up your forces inside of a scenario. The deeper into the campaign, the more powerful the reinforcing army will be. Be prepared to deal with the additional challenge of this enemy's army during the scenario. The presence of an enemy leader icon indicates a supporting army is reinforcing the scenario. It is important to take careful stock of the situation.

It is important to remember that unlike multiplayer, the goals of a single-player scenario can differ quite a bit from scenario to scenario.
