Get 200 total kills, win 50 Matches, get 50 kills with lethal scorestreaks (RC-XD & Sentry Turret recommended), 10 Squad Wipe Medals (play Fireteam), 100 kills from vehicles (play Combined Arms Moshpit / Fireteam). There are just 5 Multiplayer trophies and they are relatively easy and self-explanatory. After getting one ending, replay the 2nd last mission “Identity Crisis” and pick the opposite dialogue for the remaining ending. What ending mission you get is determined by your final dialogue choice or in the 2nd last mission “Identity Crisis”.
Also, there are two different endings, each unlocking its own trophy. The evidence you collect isn’t relevant for trophies so you can skip that. You can still replay all Missions after the campaign.
Scorched Earth II – Mission: The Final Countdown. The Red Door – Mission: Break on Through. Mind Trip – Mission: Break on Through (*do the “Obey Adler” objectives on Veteran, replay it on Recruit after the campaign for “Disobey Adler” objectives to get this trophy). EVERYONNNNNNEE! – Mission: End of the Line. Explosive Finish – Mission: Echoes of a Cold War. Patriot Arrow – Mission: Echoes of a Cold War. Firing Range – Mission: Redlight, Greenlight. The hardest part for the platinum is beating 64 rounds in Dead Ops Arcade (in one sitting) for the trophy “Reunited with Fidolina”. So you could start with Zombies, or Campaign, or do Multiplayer first. You can go through these categories in any order you like. Welcome to the Call of Duty: Black Ops Cold War Trophy Guide! The Trophies in COD BO Cold War are split into 4 Categories: Campaign, Multiplayer, Dead Ops Arcade, Zombies. Free-Roam / Level Select after Story?: Yes, there’s Mission Select after campaign, everything can be replayed. Does difficulty affect trophies?: Yes, must beat campaign on Veteran difficulty. A possible workaround may be to disconnect your Activision Account from your PSN Account and start all over to reset your online progress. Because the progress is stored online they will already be unlocked and the trophy doesn’t auto-pop. Glitched trophies: 0 – However, some players reported if you already unlocked all Zombies Perk Upgrades & Skill Upgrades on PS4 you can no longer earn their related trophies on the PS5 version (or vice versa). Approximate amount of time to platinum: 35-45 Hours. Call of Duty: Black Ops Cold War Trophy Roadmap
