Co-op Trophies

The two trophies that need other players: join a co-op session, then 100 kills with at least two others in it.

Two trophies can't be earned alone. Both belong to the base game, so the Platinum waits on them, and neither can be missed: co-op stays open for the whole game, after the credits too. Do them whenever you like. Co-op is also the way back to a few things a save can lose: joining another player's game lets you pick up a collectible from a story area or quest your own save has closed, though never from the prologue.

Starting a co-op session

Co-op opens once the prologue is over, and a session holds up to four players. Open the pause menu, then press the same button again for the online menu. There, Quick Join puts you in a random game, Find Game lists open sessions with each host's current quest, City Alignment and number of players, and you can invite a friend instead. PS4 and PS5 players can play together, and so can Xbox One and Xbox Series players (since update 1.9.0); don't count on PlayStation, Xbox and Steam players joining each other.

That's Teamwork!: 100 kills in a 3- or 4-player sessionAchievement
Location
Old Villedor · Any co-op session – Team up with two or three friends, or in Find Game pick a session that already shows 2/4 or 3/4 players so your arrival makes three or four. Then hunt infected and enemies around the host's world until the trophy pops. To be safe, make all 100 kills in the same session.
Summary
Kill 100 enemies, humans or infected, while at least three players are in the session, you included. Kills with only one other player don't count.

About this guide

Two runs on any difficulty. Run 1 plays the whole story with every collectible, gives all seven facilities to the Survivors and ends with one ending; a save backup made outside the game at the last door before the finale lets you watch a second ending by replaying only the last two quests, not the whole game. After the credits the city stays open for cleanup and Bloody Ties. Run 2 is New Game+ on the other faction's path for the third ending. The game has no manual saves, so the backup steps say how to copy your save on each platform; without them, each extra ending needs another New Game+ run. Two trophies need other players.
