Introduction
Rochard is a 2D action platforming game with puzzle elements based on gravity manipulation mechanics.
You play as John Rochard, the head of a spectacularly unsuccessful mining outfit that makes a very strange discovery, a discovery that brings unwanted attention to the team and plunges them into danger...
Step One: play through the game
There are no difficulty settings in the game, so simply start a new game and get playing: make sure to find as many collectibles as you can, and be mindful of the few specialized kill-related trophies in the game. A single playthrough will take you anywhere from around 6-10 hours, with the variability of that time pretty much depending on your ability to figure out some relatively straightforward puzzles.
At the end of the game you're likely to have every trophy except for Death on Delivery, and - if you missed any of the 92 collectibles - 100% Gold Collectibles Found and Pack Rat. Also, you obviously won't have the Speed Run trophy which will require a second playthrough.
Step Two: cleanup via chapter select
I highly recommend finishing off all other trophies before moving on to the speed run: if you missed any collectibles, then find them now - you can check how many collectibles you've found per chapter in the chapter select menu. If you need any help finding or getting to any of the collectibles, then click here - Rochard: collectible and upgrade guide - for a complete collectible guide.
Also, if you've missed out on any kills - particularly the kills relating to the Death on Delivery trophy - then work on those via chapter select as well.
There are two reasons for cleaning up the trophies before going for the speed run: first, it's just so you don't have anything else on your mind while playing through the speed run - you can skip several fights and will want to do so and will not, therefore, want to be thinking about getting a kill-related trophy whilst blitzing your way through the game; second, you might want to refresh your memory of the early levels in order to get ready for the speed run - my experience is that the later levels of a game are always easier (and easier to remember) than the first levels when you're just starting out and getting used to how the game plays.
Step Three: speed run
You now need to complete the game in 3 hours or less. This shouldn't pose much of a problem for the vast majority of players - the game is pretty straightforward, and with all other trophies taken care of and nothing else to distract you, things should go pretty smoothly. For a couple of tips and warnings pertaining to the speed run, please see the trophy description for that trophy - which is called, appropriately enough, Speed Run.
