Age of Origins Infinite Zombies
Age of Origins Giant Cannon
Age of Origins Alliance Bounty Event
This event is the best place to upgrade your city. Instead of using your upgrades when you get them, save everything for this event so that you can get rewards for spending upgrades. Save all: Officer xp, officer purple fragments, officer skill xp, titan xp, titan evolution, titan skills, extension components, flowers, speedups, materials, gold.
You get tasks to complete to gain points, 4 tasks are given a day for free and 4 more can be purchased. The event lasts 5 days. I never need to buy extra tasks to collect the full rewards but you will if you want top rank. The $9.99 for extra rewards is one of the best deals in the game if you unlock everything. You can recycle titan talent points to continue to do the quest.
To win top 50 you must only do 5 star and buy all extra rewards each day. To win, try to refresh until you get the 650/600 events or only buy packs for each quest. Maximum score is 32,500 if you buy packs for every quest. I can usually do all 5 star quests each day and get top 50 for the 1 day dragon skin which is really pretty and gives attack boost!
