It would be in your best interest to have at least beaten Mephisto (i.e. The area I would suggest doing this on is Mephisto's Realm, specifically the section right after you get Ghost Rider (Sepulcher). If you set up a dummy account, you can get this, as well as all the other arcade achievements without ever touching the online portion of the game. The good news is you do not actually need another person to get this done, just another controller. There are a couple of ways to get this done, and unfortunately neither of them are 'easy'.as in 'not time consuming'. If you haven't already obtained any Arcade related achievements you will also unlock the following: All you have to do now is reload your save and repeat the process a total of 100 times. Now your game is saved, you can simply use your main character to enter the lift and kill the 4 enemies you gathered up and then re-enter the command deck again thus counting as a level complete and netting you a win. Characters with an area of effect works best but any character will do. Once set up, simply save the game in this state.

Next you are going to have your character that is going for the Arcade wins next to the orange marker and have the second character hovering over the save point. Once they are nearby the entrance, re-enter back to where the save point was. What you are going to need to do is go through the orange marker located on the map and try to round up at least 4 enemies near the lift you just came from and bring them to the entrance (command deck). You will eventually come to your first 'Save Point' on the ground. Play on arcade mode with two controllers, avoiding all enemies up to the point in which you meet Scorpion for the first time.

Start up a new game (with or without stats). Here is a super fast way of obtaining this achievement which only took me approx 30-40 mins.
