Unlike the first Crysis and Crysis 3, this sequel requires a lot of online grinding. You'll need to play the campaign at least once - though more likely you'll be playing it twice, once on easy and once on Supersoldier - as well as finding collectibles along the way.

There are 15 online trophies to gather, one of which - Crysis, What Crysis? - requires you to reach the highest online rank, which will take you about 60 hours of multiplayer, depending on your skills. In addition, the Dedication trophy requires you to play an online ranked match six months after the first time you logged in. This means, the minimum amount of time you can obtain the platinum is six months.

Since you'll need to wait six months to claim the Dedication trophy, we recommend hopping onto multiplayer and completing your first ranked game. This will start the clock.

Next, start up the campaign. While it's possible to collect all the trophies in one playthrough, we recommend playing first on Easy. This will not only make things easier as you try to collect other trophies along the way, but you can then carry over all your upgrades to a New Game+ which will make completing it on Supersoldier much easier.

Along the way, you'll need to find all 18 statues, one in each of the eighteen levels, for The Tourist trophy. Check out the walkthroughs under our Links tab for help with their locations. Also, there are 5 level-specific trophies to watch out for: Food For Thought in chapter 2, Hole In One in chapter 9, Band Of Brothers in chapter 10, Literary Agent in chapter 12, and Stealth Assassin in chapter 16. Check out the Crysis 2 trophy guide links under our Links tab for further details.

Once all the campaign-related trophies are out of the way, you can head back into multiplayer. This is where all the grinding will come in, as you boost your character's level to the max - rank 50 - for the Crysis, What Crysis? trophy, while collecting others along the way. This will take you roughly 60 hours of online gameplay, depending on your skills.

Finally, if you happen to get all the online trophies before the six months is up, remember to pop back in half a year after your first played ranked game to play another, in order to claim the Dedication trophy - and your Platinum.
