Hi Everyone! I found a much easier way to complete this achievement, though it'll take a little preparation and a friend it make it work.
First, you need to unlock and build the Limbo warframe, you'll acquire all of his parts and blue print by completing the Limbo Theorem quest which is acquired after completing The Europa Junction on Jupiter. It also requires an Archwing to complete the quest.
Once you have Limbo built, find a friend that also has Limbo built, and head to the Plains of Eidolon on Earth.
Limbo has a special ability on his
that allows him to jump inside another dimension called the Rift. While in the Rift, most enemies can't touch you, and while you can't hack consoles or pickup loot that's dropped, you can revive other players!
So once you're in the Plains, find a group of Grineer, the more the better, and have one Limbo stand there and take the beatings while the other goes into the Rift and stands by their friend. As the "real world" Limbo takes a beating and gets knocked down, the Rift Limbo can immediately revive them while taking no damage themselves! For a reference point, myself and another gamer got this done last night, ran about 100 revives in about 20-30 minutes.
Good luck Tenno!
