How to unlock the Lifesaver achievement in BINARY DOMAIN - Definitive Guide
If you want to stop them healing themselves then don't buy them health packs at shops, if you're the only person with health packs then you'll have to do the healing.
Also this seems to be cumulative across playthroughs as I got it on my second revive on my second playthrough.
This trophy can be earned in campaign or in multiplayer. Purchase or pick up a first-aid kit, approach a downed teammate and press . I got this trophy online while working on my Versus revive challenges, which is probably more efficient than attempting to get it in campaign. Teammates in campaign often have their own meds, and I had very few chances to actually heal them. You may want to equip Nanos that increase your first-aid kit capacity and remove Nanos that raise your teammates' health, defense, and meds capacity. Revives are cumulative and carry over into chapter select and additional playthroughs.
This is technically missable but this does accumulate through playthroughs so don’t worry if you don’t get it at first. Simply keep some first-aid kits on you; some enemies will do a heavy number on your team mates. They will sometimes call for you but usually the case is they will heal themselves if they have a first-aid kit. So best thing to do is not to give them first-aid kits, and let them fight, this can prove difficult though as if you don’t fight much it could lower trust. I managed to do a fair bit of healing against the mobile missile robot in the tunnel and against the Gorilla bot.
