How to unlock the Survivor achievement in Legendary - Definitive Guide
After starting a match, stay at the spawn point. The opposing team can't reach you, so you can't die while you are there. The achievement will unlock when the match finishes.
Just like the description says you have to be playing a 4 vs. 4 match and you CAN NOT die. Obviously, boosting this achievement is very helpful, but it can be done without boosting. Stay in your base at the start of the game! Don't leave, don't attack the werewolves, don't attack the other human players and don't throw grenades. You also DO NOT have to win the game only finish it and do not die. As with the other 4 vs 4 achievements, if someone drops out you do not unlock it.
