Progress until you can purchase the Sprint – Wall Running Power. Enter an area with a ceiling, such as a tunnel, bridge underpass, building interior, or a building overhang. The ceiling must be reachable using a wall. Wallrun up the wall until your character reaches the top and gets pushed off. Repeat the process ten times.
Find lava flows that drop down from the floating islands in the sky. Fly through them a few times while traveling fast in order to cover a lot of distance.
Hold the LMG (with its Toughness ability) at full health and begin walking on lava. This should leave you with a small amount of health, and will allow you to walk away after earning "Soft Shoe".
Find a motorcycle and take it to the lobby. Clear all enemies in Extraction Facility and capture two points. Capture the last one when you are on the motorcycle. Note: You still can use machine guns.
At level 15, purchase Secrets Finder for 10,000 wages. Open the map and select "Collectibles". Filter everything else to have it show where all the books are located. When looking at the mini map, when a book is at the same height as your character it will no longer appear opaque.
Until the first helicopter appears, Tag probably will not take any damage. Once the helicopters appear, destroy them as soon as possible. Tanks will eventually begin to appear together with the helicopters. They are less likely to hit Tag from down there; focus on the helicopters and occasionally shoot a missile at the tanks. Consider shooting without the lock-on ability of the rocket launcher to make faster shots. Fire as many rockets as possible.
Note: Do not destroy all the spires before attempting this, or you will need to start a new game. Find a spire and hover directly over the top of it. Just as it launches the missile, press [Blast] to shoot it down. Flying around at higher altitudes is not recommended due to the unpredictable flight of the missiles, in addition to the difficulty of hitting a fast moving target.
You must climb to the very top of Blackbeard's ship, located near the southeast corner of the map early in the game. Start from the center of the ship and perform walljumps to reach the platforms above. After standing on the highest platform, execute a final jump that requires a quick in-air adjustment to land on the very top of the mast .
Stand on some lava and allow it to bring Johnny Gat's health down. Ignore the "Warp back to shore" message and remain there for some time until a reference to the Terminator's "thumbs up" while sinking into lava appears.
