Topic: Upgrades to outposts & big pew pew
Being able to upgrade in some way an outpost you own would be pretty cool. Perhaps people in the guild could 'donate' spare (haha) ep thay have to buy each level of the upgrade. If an outpost is lost the upgrades get reset.
One of the upgrades could be a cannon right on top of the tower. Long range, good line of sight, able to fire on enemy from afar. Muhahahahaaa.
