Wave #14 -- 19:31 Note: If you think you can do the headshots, do it. My way is slow but safe.
Wave #15* -- 23:13

Gear equipped
~ Burning Halo
~ Bullet Boon

Note: All my weapons and Vigors have been fully upgraded. This can be done easily if you play through all the arenas (especially the fourth) and only bother with the ribbons you think you can get.

This isn't flawless completion of the whole arena. However, the blue ribbons add up so you don't have to take all in one run, you can leave the hardest ones for another try. In the end it counts as 15.

Wave #1 -- 00:00
Wave #2 -- 01:00 Note: Take out the Fireman first and make sure you have salts to keep the patriot possessed.
Wave #3 -- 03:45
Wave #4 -- 05:55 Note: I find that Crows Vigor is the best for this one as if an enemy dies from the trap, a new trap will be automatically created on their body (requires an upgrade).
Wave #5 -- 08:52
Wave #6 -- 09:55
Wave #7 -- 11:40
Wave #8 -- 13:10 Note: You can damage enemies but make sure you don't kill them like me.
Wave #9 -- 17:27 Note: Be careful with weapons and Vigors which do splash damage.
Wave #10 -- 21:40
Wave #11 -- 23:40
Wave #12 -- 26:00 Note: Sometimes enemies tend to be suicidal and jump off when the wave starts. Use traps which keep them busy (Crows and Shock Jockey).
Wave #13* -- 28:05
Wave #14 -- 29:00
Wave #15 -- 31:55 Note: Make sure you take out everyone outside the engine room. Once you destroy the engine, just jump off the zeppelin and the wave will end. You don't have to kill everyone inside the engine room.

This isn't flawless completion of the whole arena. However, the blue ribbons add up so you don't have to take all in one run, you can leave the hardest ones for another try. In the end it counts as 15.

Wave #1 -- 00:00
Wave #2 -- 01:15 Note: Try not to leave the ship as it may cause your blue ribbon to fail for some reason.
Wave #3 -- 03:20
Wave #4 -- 04:45
Wave #5 -- 07:05 Note: Try to keep the Handyman busy and possibly to make him face you in a direction with no enemies behind you. His bash may kill them and that will fail your blue ribbon.
Wave #6 -- 08:30
Wave #7 -- 10:35
Wave #8 -- 13:45
Wave #9 -- 17:35 Note: I recommend opening the Salts tear in the beginning in case you run out of salts.
Wave #10 -- 18:49
Wave #11 -- 20:50
Wave #12 -- 22:48
Wave #13 -- 24:05 Note: Make sure to shoot the enemies while they are aiming (for snipers) and shooting at the decoy (for the Patriots). Take your time and try to bait the enemies to the decoys if necessary.
Wave #14 -- 29:13 Note: The enemies have Machine Gun, RPG and Shotgun. I can confirm that you can find both RPG and Shotgun on the level via tears. You can use Return to Sender to defend from any damage as long as you don't hit anyone with it.
Wave #15 -- 33:20 Note: The Handyman committed suicide in my case. However if he doesn't do that you can cause him to throw the Firemen at you, which will kill them and then you can shoot him with whatever you like. You can find weapons on the level via tears.

This isn't flawless completion of the whole arena. However, the blue ribbons add up so you don't have to take all in one run, you can leave the hardest ones for another try. In the end it counts as 15.

Wave #1 -- 00:00
Wave #2 -- 01:18 Note: Be very patient. Sometimes enemies just don't want to use the sky-lines.
Wave #3 -- 03:19 Note: Just try not to die. If necessary, draw the enemies near the Tesla Coil.
Wave #4 -- 06:21
Wave #5 -- 09:31 Note: Use the left side of the balcony to draw the Handymen's attention if they simply stand and don't move for a while.
Wave #6 -- 13:42
Wave #7 -- 16:01
Wave #8 -- 18:51
Wave #9 -- 20:08 Note: The blue ribbon will appear once you kill everyone, not after you kill the Siren.
Wave #10 -- 22:42 Note: Try to play more conservatively and preserve your ammo. Don't waste it recklessly like me. If you do, simply make sure you buy a door and let the enemies kill you. You will respawn with full ammo.
Wave #11 -- 25:30 Be very patient. Take most of both Handymen's health and hit them only once while they are distracted with the Booker decoy. Eventually you will kill them. If you hit them more, you risk killing them after they've killed the decoy and that will fail your ribbon.
Wave #12 -- 29:40 One of the Crows disappears in my case. I have no idea why that happens, but you can see how I kill the other one. Kill them both the same way unless yours disappears as well. Don't use equipment that adds fire to your hook or electricity when you are hit as it may cause your ribbon to fail.
Wave #13 -- 33:30 There are three types of soldiers here. Soldiers with Pistol, ones with Machine Gun and ones with Shotgun. I recommend picking up Machine Gun and Shotgun because these enemies are more and they do more damage. Taking them out will leave you with a few Pistol ladies. Use the turrets to kill them. It may take some time so be patient.
Wave #14 -- 38:10
Wave #15 -- 39:44 Just watch out where the Siren appears. As soon as you spot her use the Charge Vigor to get to her quickly then Undertow the bodies she is trying to resurrect.

Gear equipped
~ Burning Halo (Waves 1-6, 8, 10, 11) / Hill Runner's Hat* (Waves 7, 12-15)
~ Bullet Boon
~ Vampire's Embrace
~ Head Master

Note: All my weapons and Vigors have been fully upgraded. This can be done easily if you play through all the arenas (especially the fourth) and only bother with the ribbons you think you can get.

----------
*I only recommend NOT using Burning Halo gear on Waves #4 and #12 since the fire on your sky hook counts as Devil's Kiss and MAY cause some blue ribbons to fail. Note that I still use it on Wave #4 and have no problems.
