To get this achievement you have to spend 2 hours with homies from the past saints row games. The homies you must call are
You can call 1, 2, or 3 homies but it doesn't matter it doesn't go faster or slower.
You can also just whistle over members from your gang and that counts towards the achievement credit to loadsmorewubwub for finding this out.
You cant be in missions and must be in the simulation.
You can jump on a building and go eat or watch T.V. or go take a bath if you dont wanna walk around with your homies. You can go get collectibles and hack stores and your homies teleport to you so you dont have to wait for them to catch up.
Hopes this helps pm me or comment if you have any questions or anything to add to the solution. If you give me a negative vote please comment or pm why so i can fix it.
