How to unlock the Everybody Dies achievement in RESIDENT EVIL 6 - Definitive Guide
AI kills count toward your total as well. So if you're playing as the human protecting the BSAA, any computer enemies you kill, as well as human controlled creatures, will add to the tally.
editing the guide to suggest Catacombs for the boosting map instead of Steel Beast. It's a small map with a perfectly placed spike trap that both players can use to knock the achievement out in a few hours.
BraveZach from the comments hit it on the head:
NOTE: The achievement description is misleading. The 100 creature kills do not need to be player-controlled. Killing AI-controlled creatures/zombies counts towards your total.
Steel Beast is an ideal map to boost this because the J'avo run faster than the standard zombies on the other maps. When the match begins, choose a safe meeting point where the kills will be boosted, like the corner of the catwalks beneath the bridge. Players who spawn as the Creatures should focus on working towards their 100 Human kills, since you can kill AI-controlled creatures at a later time. The Human player will spawn in that same corner of the catwalk every time they die, which will allow you to obtain about 2-4 kills before the Rookie Agent dies. Make sure you do the Dash-Attack to kill the Human faster. If boosted with more than one player, you can net 5+ kills per round.
This achievement is cumulative and will unlock once you have killed both 100 player-controlled humans, and 100 creatures. You can check your progress by opening the Records in the Main Menu and going to 'Extra Content -> Siege -> Agent Kills/Creatures Kills.'
Specifically: both choose an agent and a card - a steel beast. The player playing as the agent, to speed up the procedure, runs up to his BSAA bot, and the booster player (monster) kills him, and then the BSAA bot, in the next round, vice versa.
IMPORTANT:
1) it is better for each player to choose the last battle skill, in which case he will knock the Agent (player) to the floor in 2 hits, and not in 6
2) do not forget that the booster in the second round will be given the same amount of time to fight as the first player completed the round, so the first player must give his partner a head start in time, I advise 1 minute. do the first round, then the second booster in the second round will definitely have time
3) when the booster player (monster) kills you, you will rejoice, do not waste time and kill ordinary monsters for a trophy while your partner is poking a knife at the BSAA bot
p/s Approximately these 2 trophies will take 200 minutes (100+100) time for rounds + 65 minutes. for loading. Total: about 5 hours for two
Siege mode, where you need to cover a BSAA agent
With the creatures everything is clear, cover the agent and shoot as many zombies as possible. For example, I was able to shoot about 15 pieces in a round (as mentioned earlier, it is not necessary to kill the enemy your partner is playing for). So 100 pcs. accumulate without problems.
But with the murders of agents it is already more difficult, but not everything is so hopeless. You also choose a private 1 on 1 match. Place the map “On the Rooftops”. This is the most convenient and effective card for boosting this trophy. Set the perk to “Last Fight”. The situation is such that the agent whose agent needs to be protected is on the helipad, and you and your partner appear at the very bottom (only at different points). Meet at the stairs to this very platform on the right side. Because the Agent for whom you play and who must be chewed in this round after death will appear exactly here. It turns out that you can boost without leaving the cash register and without wasting precious time. And so the infected pounces on you and gnaws at you, and at this time you do not resist and are already on the verge of death, and your partner comes up and finishes you off. And you immediately appear behind him. I killed about 6 times per round. And since the zombies here are slow, they won’t get to the agent on the roof so quickly and you’ll have time to do everything.
