The game was released on march 6, 2012. Over a year later, on September 15, 2013, the online servers were closed. MLB 12: The Show includes 3 online-related trophies, which are now unlockable. Therefore, the Platinum for this game has become Not Obtainable.

The newly added Diamond Dynasty mode requires online access, to which there are three trophies related to this mode: Collector, A Year In The Life, and Masterpiece. Since the online servers were closed on September 15, 2013, these three trophies can no longer be unlocked. Therefore, the Platinum trophy for MLB 12: The Show is now Not Obtainable. However, there are still 31 offline trophies that can be unlocked, so if you're still interested, then read on.

You can play and earn trophies in any order of your choosing without the need of a roadmap. Though you will be spending the majority of your time in Exhibition mode. Your ultimate goal is to unlock the Everyone's A Winner for having played a game with each of the 30 Major League teams. You can work on other trophies during this process, so be sure to check out the MLB 12 The Show trophy guide links under our Links tab to see what you need and their requirements. We specifically recommend playing in Miami until you've managed to hit the aquarium behind home plate for the Fish Off A Barrel trophy.

Once that's completed, you can head into Home Run Derby to work on their related trophies. This includes hitting 10 consecutive home runs for the Winning trophy, which is perhaps the most challenging in the game. Remember to edit the players to give them the most power. This trophy is a combination of timing and some luck.

After that, simply mop-up any remaining offline trophies you still need. Remember to check the MLB 12 The Show trophy guide links to see what you're missing and their requirements.

Unfortunately, with the servers now offline, this is as far as we can go.

The game was released on March 8, 2011. Over a year later, on May 10, 2012, the online servers were closed. MLB 11: The Show includes 4 online trophies, which are now unlockable. Therefore, the Platinum for this game has become Not Obtainable.

Since the servers were closed on May 10, 2012, the 4 offline trophies cannot be collected, which means the Platinum for the game is Not Obtainable. However, there are still 31 offline trophies that can be unlocked, so if you're interested, then read on.

There are two co-op trophies you can unlock right away if you have a second controller. Plus in another controller, and win a game for the Cooperation trophy. For the Advanced Cooperation trophy, you'll need to complete a strike 'em out throw 'em out double play. Check out the MLB 11 The Show trophy guide links under our Links tab for more details.

There are essentially two career paths you'll need to take, one for batting and the other for pitching, in order to unlock the Batting Performance Evaluated and Pitching Performance Evaluated trophies respectively, while working towards the other RttS trophies.

After that, there are the Seasons trophies. You'll need to play as the Cubs for The Billy Goat trophy. Most of these games can be simulated, except for hitting a Home Run on Mother's Day with a pink bat for Momma's Boy, and hitting a triple on Father's Day for the Daddy Long Legs trophy.

Last, simply check out the trophy guides under our Links tab for whatever you're missing, and mop-up the remaining offline trophies. Unfortunately, with the servers shut down, this is as far as you can go.

The game was released on March 2, 2010. Almost exactly one year later, the online servers were closed. MLB 10: The Show contains 3 online trophies, which are now unlockable. Therefore, the Platinum for this game has become Not Obtainable.

The online servers were closed on March 21, 2011, which means the 3 online trophies are no longer unlockable, making the Platinum Not Obtainable. However, there are still 40 other trophies you can earn offline, so if you're interested, then read on.

There are a few missable trophies to watch out for. We recommend beginning as a catcher in RTTS mode, and focus on calling a pitchout on a steal attempt for the Timing Is Everything trophy, call a quality start for the Call It trophy, and throw out two runners attempting to steal a base for the Stolen Thunder trophy. Once these three trophies are out of the way, you can simulate the rest of the career. Next, you'll want to aim for the Make The Call...Again trophy. This one requires a bit of strategy and explaining, so check out the MLB 10 The Show trophy guide links under our Links tab. Finally, continue the career and work on unlocking Professional Trainer, RTTS Derby, Mr October, and the RTTS Back To Back trophies. Last, start a new RTTS as a pitcher, and work on unlocking the Sim Game and RTTS Road Warrior trophies.

With that done, if you like, you can go for the Around The World trophy by starting a season. To make things quicker, set each game for 1 inning, and simulate the first 82 games During this process, you can also unlock the Contender, Pennant Race, and Victory Is Mine trophies.

After all that, it's just a matter of mopping-up anything you're still missing. Be sure to check out the MLB 10 The Show trophy guide links under our Links tab for details on what you're missing and how to get it.

Unfortunately, with the servers closed, this is as far as we go.

This game would have been a difficult Platinum to begin with. However, on March 17, 2010, a year after the game's release, the online servers were shut down. The game includes 3 online trophies, which can no longer be unlocked, resulting in the Platinum being Not Obtainable.

With the servers shut down, the 3 online trophies are now unlockable, making this Platinum Not Obtainable. However, there are still 26 offline trophies you can collect, so if you're interested, read on.

First, to make life easier, you can adjust the sliders so that yours are turned up, while the CPU is down, and select Rookie difficulty.

Then, you can start a Franchise team and work towards unlocking the Streaker trophy for getting 10 game wins, and the Managerial trophy.

After that, start up a Road to the Show and begin by selecting a non-pitcher position. You should still be playing on Rookie mode, but as you get a feel for the game, switch to All Star difficulty. Focus on achieving all the goals and boosting your stats, and aim for the RttS MVP trophy.

Then, start another Road to the Show, this time selecting a pitcher. Again, switch the difficulty back to Rookie, until you've knocked out the majority of the trophies. Once this is done, the rest is mopping up.
