Tips and Tricks
Walls are a basic and effective form of defense best suited to protecting valuable targets. Upgrading walls increase their health so best stick with that as much as you can.
Another great defensive strategy is by using Shield Generators. They form a deflective radius around themselves protecting anything inside from damage until the generator is destroyed or the shield is collapsed. Again upgrading a shield generator increases the shields health and radius and as time goes by and enemy forces are getting stronger it is a necessity to upgrade all your defenses.
Rapid Fire Turrets are a good general purpose; single target; medium damage turret that is moderately good against most targets.
Mortars lob explosive bundles in an arc at incoming enemies dealing moderate damage to a medium area.
Burst Turrets are manned by groups of infantry using mounted guns. They are highly effective against single targets.
The Unit Transport are where your infantry and vehicles are stored prior to being deployed in battle.
Keep in mind Heroes must be recruited after each time they are used. They add up to your army strength.
Alloy and Credits are the resources you need in this game.
