Your heroes do the bombing. You keep the loot.
Close the tab and your heroes stop working. Every one of them falls asleep until you come back.
Auto Farm keeps them going while you are away. They bomb until they drop, take a bed, wake up and go straight back out, and a rested hero steps in whenever one runs dry.
Into the game treasury, and back out as rewards. Every coin you spend on a pack, a fusion, a level or Auto Farm goes into the same pot that pays for the chests your heroes crack open. Nothing new is ever minted — the same coins keep moving between players.
Coins earned in the last 24 hours cost 30% to claim right away. Wait a day and you keep every coin. The game always shows you the exact cut before you press anything, and the withheld part goes back into the treasury that pays future rewards.
No. Your heroes pick their own targets and bomb on their own. All you decide is who goes to work and who goes to bed.
Never. They do not fight and nothing on the map can hurt them. The only thing that stops a hero is running out of stamina.
It drops where it stands and starts recovering. If you have a rested hero spare, that one walks on and takes over, so the map keeps clearing.
Packs hand out the lower ranks. The top two you cannot buy at all. The only way to get one is to fuse your way up to it.
It takes two heroes of the same rank and gives you one of the rank above. The two you put in are gone for good, and the new one keeps some of their abilities and rolls the rest fresh.
A hero in a bed wakes up far sooner than one asleep on the ground, so houses are how you keep the crew working instead of waiting. There is a fixed number of them and no more will ever be built.
Packs, houses, levelling up the heroes you keep, and the fee every fusion charges.
No. Heroes stay on your account. The coin is the only thing that moves.
Normally yes. Close it and every hero falls asleep until you come back. If you would rather not babysit it, Auto Farm is the paid option: buy it from the red button on the map and the crew keeps cycling on its own until the timer runs out, whether the tab is open or not.
