The game has multiple stores that allow to exchange items like diamonds and alliance contribution points.
To be able to keep up with other players and grow and become strong it is fundamental to use the resources properly and to buy the right items.
Some items become available after reaching a specific VIP level or when entering season 1/2, here you can find the most complete list of items in stores.

Diamond Store
This is the base store of the game, I suggest you don’t buy any item here (if you need a trade contract to change trucks rewards you can do it from the truck section directly).
This store NEVER resets and all its items are unlimited.
The only items that should be bought here when they are sold out in the other stores are:
- Advanced Teleporter
- Alliance Teleporter
VIP shop
In this shop there are some of the most useful items to grow fast, but they require you to have available a lot of diamonds. IMPORTANT: use diamonds wisely, first buy VIP and then come here to buy items.
This store resets weekly and has a limited number of items.
My suggestion of purchases are the following, from most important to less important:
- Stamina
- Universal Legenday Hero Shards
- 8H Speedups
- 3H Speedups
- 1H Speedups
With this purchase you will need: 5*60+10*300+10*480+20*192+60*72= 16.260 Diamonds
Additionally I would suggest to also buy Epic Hero Universal Shards 
if you have additional 6.000 Diamonds.
Alliance Store
This store is really helpful because you can use your Alliance Contribution points to buy items.
My suggestion for alliance shop depends on how old your server is.
I always go in this order since I focus on hero,construction and research growth:
- UR shards
- construction speed ups
- research speed ups
- drone parts
But most importantly, be always sure you have enough shields for Saturday! At least 1 24h and 1 8h.
I never buy:
- survivors
- resources chest, they are super over priced
- superalloy
- dialetric ceramic
During Season 1/2 I also give priority to Mason and Violet shards before the UR upgrade.
And now that the transfer feature is open consider buying the transfer tickets if you want to move.
[soon an updated version will be provided, that adds season1/2 items]
Honor Shop
The Honor Shop is where you exchange your Honor Points for really important items.
This Shop resets monthly
SUGGESTION: Only buy Gear Blueprint Legendary 
in this shop, as this is the only place where you can get them without spending real money and you will need a lot of them to improve your gears
Please note that the monthly limit of Gear Blueprint Legendary is 50, not 41 as seen in the picture above.
Campaign Store
In this store you can buy items using the Campaign Medals 
, that you can earn in the Honorable Campaign (previously they were under the yellow helicopter, now they are at the alert tower).
Here more details about some of the items:
My suggestion is to buy at least these items in this order:
- Epic Resource Choice Chest -> This is where if you are HQ level 30 you can earn 165 M gold each week!
- Legendary Campaign Chest -> If you are lucky you win 100 golden shards
- Drone Parts
- Universal Exclusive Weapon Shards
Season Store
This store is available only after 
Season 1 – The Crimson Plague.
