It‘s been too long for me to have any personal tips, but trueachievements (website) has a walkthrough for it and their walkthroughs are usually an easy ticket to platinum. Just google „game name trueachievements“ and look for the „Walkthrough“ link on top. If there‘s an asterisk next to it, it means someone‘s posted a full achievement walkthrough.

It also helps gauging how long it‘ll take since they give you number of playthroughs required and estimated time in the overview.

You can also look up specific achievements on there where people post different strategies and/or cheese.

The site‘s for Xbox but big games usually have achievement parity across different versions so it‘s the same for PS/PC.
