Trophy Hunter
Batman Arkham Asylum is a fine release from Rocksteady Studios in 2009 and it is still fantastic to enjoy on the PlayStation 3 to this day. Whilst there are newer ways to play it, it still performs well on the PlayStation 3 hardware and copies can be picked up for less than £5 in the UK and around $7 in the US. The Platinum Trophy is still available as there are no online requirements and it's a nice platinum to have to showcase your skill as a gamer.
Let's start with the good things, this is a single run Platinum Trophy, no multiple playthroughs are required and all collectables are available at the end and to make it even simpler, the collectables are on the in-game map, so you don't need to keep consulting an online map.
Missable Trophies are those that would require a second playthrough of the game.
At some point in the game during the story you will be in a room filled with toxic gas. You need to find and save all the guards and one bad guy before turning the gas off to get this trophy. Which is odd considering turning the gas off would save them anyway?
This one is right near the end of the game. Without too many spoilers there will be a bunch of non-hostile guards waiting for you. It is easy to walk past them but no, for this you need to take them all out. This is also a good place to try for the trophy below Freeflow Combo 40
. This is a trophy that requires pretty decent mastery of the controls. You need to keep your combo going to 40 hits which means hitting enemies consistently within a small window and also not getting hit yourself. In order to even attempt this you need a lot of enemies around you which is why it is best to try and get it along with Party Pooper. Make sure to consult a guide for these and they won't ruin the story by looking them up in advance.
The next set of difficulties are in the challenges. These challenges are separate to the main story but all take place within various locations from the main game. These range from combo challenges to stealth challenges and they are pretty difficult but if you are skilled and persistent you can definitely do it.
You should be looking at 20-30 hours to get the Platinum which is not too bad. It took me an impressive 10 years from obtaining the first trophy to finally getting the Platinum so if you can beat that, let us know.
