Summary
Investors can buy Crystals using BUSD. These coins can be used to unlock/buy towers and to add more warriors to each tower. The higher the tower and the more warriors hired the more daily profit will be received. There are a total of 5 towers, and each tower comes with 1 warrior and can be upgraded to a maximum of 5 warriors per tower. The warriors produce Coins, which can be sold for BUSD
An investor can sell their tower, which will set warriors count to zero (and hence no daily profit), and this will send the user the calculated profit for the next 10 days.
The Smart-Contract Audit found one potential vulnerability on the add Crystals method. The smart contract is a fork of BUSD Kingdom (and all the other Kingdoms). See code diff comparison here: https://www.diffchecker.com/bVzCASXI

BUSD_TOKEN.transferFrom(msg.sender, manager, valueToManager);
BUSD_TOKEN.transferFrom(msg.sender, address(this), value - valueToManager);
Backdoors
In an effort to add some spice into the game, the development team have added in a method that will "randomly" give the user between 0.8x and 1.5x crystals on purchase. The only flaw in this design is that the random number is literally block.number % 3 and so any script kid and his bot could use this to game the system and buy crystals only on 1.5x blocks.
There are no backdoor methods that withdraw funds to a non investor wallet.
Owner Privileges
The owner can initialize the contract to start investment.
There are no special privileges that the owner can do aside that the owner will get unused referrals which can be huge if more investment goes into the project and hasn't used a referral link from other investors.
Fees
Buy Crystal/Deposit:
· 5% in the form of ETH
· 2% in the form of crystals
Note that the owner will get crystals for unused referrals (8%), and the owner will also always get 2% of crystals bought same as what the referrer would get, which can be massive as the inflow of deposits goes to the contract. This will be considered In the scoring matrix, and as posted in the George Stamp channel, the scoring will be 1.
Complexity
Not lot of complexity within the contract.
Team Trust
Team has no known previews projects and has a small community.
Other Risk
I'm assuming Blizzard hasn't authorized use of any copyright stuff here.
Considering the complexity of the contract, at the end of the day, This is still an ROI Dapp that relies on funds invested to payout existing users. if the contract reaches $0 investors will not be paid out. Do research the project before investing.
