How to unlock the Medic! achievement in Mass Effect: Andromeda - Definitive Guide
Find a group of enemies, set the difficulty to Insanity, send your squad mates forward, let them fall, then you can lower the difficulty and revive them. You don't have to lower the difficulty of course, but there's less chance of you dying while reviving. Then just rinse and repeat. Unless you're doing an Insanity run, this method shouldn't affect anything else.
A couple extra tips:
-Remnant destroyers are an excellent enemy to farm revives with, as they're tough to kill and do a lot of damage.
-Tactical Cloak is a useful skill to use (though not essential of course) as you are less likely to get shot at while reviving if it's activated.
Get behind cover down range from these turrets and have Jaal, you know it's gotta be Jaal, stand a small ways to the front and just to the side of your cover (he's going to get blown back). Agro the turrets with some gunfire and get Jaal into position. If you find the sweet spot he'll eventually get knocked down in a single hit and knocked just to your side so you can revive him while safely behind cover over and over again.
Be sure to have your second squad mate stand as far away as you can and incase you've forgotten use left and right on the dpad to position your squad. And yes any turret will do but this one has a backup and it's easy to find. One point in the tech skill tactical cloak is useful if you need to leave cover for revives.
This can also be done in multiplayer with other members of your squad.
This trophy can be earned in single player and multiplayer, and is cumulative from both modes. When a teammate from you squad gets downed, approach them and hold to revive them. Do this 25 times and you will unlock this trophy.
In single player your teammates won't go down in lower difficulties, so change the difficulty to Insanity and tell your teammates to go attack enemies out in the open. When they go down, activate your Tactical Cloak skill (Tech Skill tree) and go revive them.
You can do this quickly in multiplayer by playing with a friend in a private match and boosting revives on each other. Check the Co-op Partners Thread to find someone to boost this trophy with.
When a teammate goes down, you will get a notification on screen of their location (a red arrow with a cross in the middle), and you'll need to hold the button near them to revive them. This is counted in both SP and MP, in any combination.
