Try out your friends' and guild members' strong heroes by hiring them as a mercenary. Learn about adding friends in Undead World: Hero Survival.
Once you have a friend or are part of a guild, navigate to the Mercenaries page by tapping on the Friends icon on the home screen.
The Mercenaries section will be the second tab at the bottom of the Friends page.
On the Mercenaries page, you will see three slots and a list of mercenaries. The mercenaries on the list are all your friends' or guild members' heroes of Epic or higher rank.
Hiring a Mercenary
Tap on a hero you would like to hire to bring up the request screen. If more than one of your friends or guild members own a hero at the same rank, tapping on the hero will bring up a list of all the players you can hire that hero from. Choose which friend or guild member you would like to request the hero from.
After you press Request, you will need to wait until your friend approves the request. You can send up to 5 mercenary requests each day.
Once a mercenary is hired, that hero will appear in one of the three slots at the top of the Mercenaries page. Underneath, you will see the name of the player you are borrowing the hero from.
Playing with Mercenaries
Every seven days, you can use a mercenary during one campaign stage and during one Skyscraper floor. All available mercenaries can also be used during one Midtown session.
Hired mercenaries appear with a yellow pawn on their hero icon.
Hiring Out Mercenaries
Tap on Manage Mercenaries in the upper-right of the Mercenaries page.
Under the Requests tab, you can view requests friends or guild members have sent you to hire your heroes. You can choose to approve or reject these requests.
On the Hired tab, you can see which heroes are currently hired out by your friends or guild members.
