Secure your borders by fortifying your outposts. This will make you stronger during battles. You can assign commanders to your Outposts and the number of commanders/outposts you can assign will be equal to your level.There is an upkeep(hourly expense) for each Outpost you equip and the price of Outpost will be subjected to inflation as you equip more of them.  {| class="wikitable"!Class!Outpost!Attack!Defence!Upkeep|-|Perimeter Defence|Blast Walls|+40|+60|+60000|}
