This achievement can be earned by reviving a total of 10 bots playing as playable characters or players by pressing and holding
near them when they get vanquished. In some cases, allies cannot be revived.
There are two ways you can earn this achievement:
1. Play PvP/Ops with bots/players using the portal, and try to camp in a hidden space, only coming out to revive a downed ally. (unless you're as good as me
, DO NOT run around like an idiot exposing yourself to danger because, believe me, there are a TON of cheaters and pros out there waiting to kill you!) You should get this achievement after a short while.
2. If you have a second controller, join a private Giddy Park server and let player 2 die from wildflower/TV head attacks then revive them. Repeat this 9 more times and BOOM, achievement.
Cheers
