This achievement may not work properly, here are the steps i took when i got this:
Game is hosted via inviting friend, not using matchmaking
Host selected the challenge
Both players enter the 5 crypts, host takes medium/big artifacts (it was enough for second player to only come to camp at the entrance of the each crypt - this may not be necessary)
Host lits the escape fire
Host comes to helicopter escape zone first (doubt it matters)
And likely at least 2 medium artifacts(codices) required, i had 3 mediums 2 larges(sarcophagis)
Achievement didn't pop up when i just collected 5 random med/big artifacts ignoring things listed above. Achievement pops for both players.
