D4: Dark Dreams Don't Die

Roland Walken only has two cases, one in episode one and one in episode two.

For these you’ll have to play a “clover touch” mini game. Clovers will fall from the top of the screen to the bottom, and you mustn’t allow any of the clovers to reach the bottom of your screen.

In episode one, talk to him after the Zapatero stunt scene. Reach 100 points to complete the first case.

Next time you encounter Roland will be after the Machinery stunt scene in episode two. Once he crawls up into that vent, keep talking to him to play clover touch again. This time you must reach a score of 200.

These games end once you reach the intended scores (100 and 200), so you can’t do the achievements for obtaining 300/800/1200 clover touch score while completing Roland’s cases.
