How to unlock the Twenty-Twenty Vision achievement in Saints Row: Gat out of Hell - Definitive Guide
This trophy is earned simply for being in game (not paused or in the menu) for 20 hours total. Depending on how efficient you are with challenges or how much time you mess around in co op you might not get this done naturally. If you do need to idle time you can simply plug in your controller and hang out in the back of the lobby of the Ultor building to get the rest of the required time if you don’t want to play the game for the remaining time. You don’t actually need to be doing anything for the time to count, just in game with the game unpaused, and the game won’t pause or boot you as long as your controller doesn't turn off.
You can see your total playtime on the first page of the stats screen.
Between the activities, missions, and challenges you should be really close to 20 hours. If not you can just leave the game idle with your controller plugged in to wrack up hours.
PS If you left the console on, then save the game manually from time to time so that your progress does not go down the drain.
