How to unlock the A friend in need achievement in Zombie Army Trilogy - Definitive Guide
If you don't have the achievement by this point, either leave one or two zombies alive in a group and take it in turns to get downed and revived/draw away the zombies and revive. Or get to the first time where you meet a Chainsaw Elite. Clear out all of the other zombies and get him to down you, simply draw him away, revive your partner, then rinse and repeat.
As the person dying you won’t have to move much at all since the fan will keep killing you.
Start a horde game on Dead End
Play a few rounds till you get the tall monsters with armor.
Let them down you and your friend revives you.
Takes prob 15 20 minutes.
Side note in case anyone doesnt know.
You CANT use friendly fire to down players, it has to be zombies
Hopefully this helps you guys out!
A co-op partner will go into a downed state when they have taken too much damage. At this point you have 60 seconds to revive them before they die, in which they return on the next wave n Horde mode or at the next checkpoint in co-op campaign. In order to revive a downed player, stand next to them and hold . It takes approximately 3-4 seconds for you to revive them. You will receive periodic progress updates on the number of revives you have performed, however, you cannot track how many you have performed in the Career Stats menu. This can be done with 2 players.
*ONLINE REQUIRED*
Fairly easy to get on higher difficulty co-op modes. A lot of players die constantly, remember you have 60 seconds, don't rush in to revive this is how most wipes occur. Clear out the enemies first and play it safe, don't want to lose your progress because you ran in too quickly!
