Hello everyone!
Most of the par time achievements are relatively easy for longtime veterans of the series but if you are new to the game, would like to see some tips on how someone else plays, or just need some background noise; I've provided a video of the level "Outskirts" and how I like to play the level that you can use for your viewing pleasure. You don't necessarily need to do the exact same things, and just run past most encounters.
***REMEMBER*** You can complete any of the game's par time requirements on
EASY difficulty if you so choose. Good luck!
