Go to the side elevator (for those who don't know where it's at, when you are coming out of the tunnel and have the front elevator to your right, you turn left, run to the end, turn right, run and you'll see it on the right). Once inside, you step on the button, go through the doors, battle the cogs there. Step on button, go through door, up the ramp and into the pipe room. Defeat both sets in there, out other door onto catwalks. Go left, up steps, then right into warehouse. Defeat cogs on raised platform, step on buttons (unlocks door, kills goons). Go through center door, then up to silos to finish up. Number of merits per room... 56 Stomper room (first room from side elevator) 56 Pipe room (each, for a total of 112) 80 Warehouse 80 East/West Silos (80 each, total of 160) 112 Center Silo -------------------------- 520 total merits These are based on dancing during an invasion. After the pipe room, if you go to the right (away from the steps) to the boiler room before going to the warehouse, you'll pick up another 64 merits (for a total of 584 merits). Here are some easy runs to remember: 464 merits - side elevator, only ONE set in the pipe room, warehouse and silos. 520 merits - side elevator, BOTH sets in the pipe room, warehouse and silos. 584 merits - side elevator, both sets in pipe room, boiler room, warehouse and silos. Sometimes it takes a few minutes to know how many of each you need to do to get all your merits, but it's well worth it. For example, 1100 merits (HW 10,17,22,32 and 42), you would do a 520 and a 584 (for a total of 1104 merits). For 5500 merits, you would do the exact same thing for 1100, just do 5 of each run. I've been able to solo the factory in about 10 minutes, with 2 runs in 25 minutes (that includes time to get more gags). A friend and a friend of theirs did a near full run in about 20 minutes to get 720 merits. My 2 runs got me 41.6 merits per minute, while they got 36 merits per minute. Keep in mind that if there had been someone with me, then we could have done 2 runs in about 20 to 22 minutes, possibly even faster. Either way, doing short runs is well worth the effort. These are the same runs that I show to my friends and the same runs that I went on to work and max my sell suit. The only times when I've gone on different runs is either when I had to, or I was just bored and went with others and followed them. I have friends that I've shown it to and they swear by it, saying that it's the all they will do now because it's not only easier, but you spend way less time in the factory, so it's more tolerable.
