Do the Races and Deliveries
When you’re first starting out in Mirror’s Edge Catalyst, you’ll probably need a little while to get accustomed to the parkour gameplay and mechanics. The best way to get comfortable with the game’s controls is to try your hand at some of the side missions available in the city of Glass. Simply pull up your map, and you should see some yellow icons, indicating races that you can attempt. There will also be NPCs standing around, asking you to do some fragile deliveries for them.
These deliveries will require you to get from one point to another within a certain time limit. They’re actually pretty challenging, so don’t expect to complete most of these on your first try. However, these will give you a good grasp of the controls, and teach you the basics of jumping and wall running.
