Saints Row: The Third/Act 4

With Steelport being controlled by STAG through highways and around Saints HQ, your going to need to go through extraordinary lengths to end both STAG and Luchadores leader Killbane from dominating the arena any further. But not without a few more twists.

Air Steelport
Follow the GPS to meet up with Viola. A cutscene will show you sneaking in. You start in the middle of the cargo. Try to open the door first. It's made of steel so Viola suggests you search the cargo for something useful. Shoot down the men in red and orange suits. Once it's clear, go to the furthest treasure marked with the yellow target to get a gadget called "Sonic Boom". It's not the famous blue speeding hedgehog! It's just a weapon with the "boom" power to open doors and later on be able to blow away items with destroying it.

Go back and open with the new weapon. Take care of more gunmen before opening the door with the new weapon again. Oops! Your new weapon has destroyed the cockpit so run to the end, ignoring more gunmen and into the tank. The next part is similar to the beginning but having a lengthy dive with a tank. Got to have lots of height to pull it off and using the parachute to land. Anyway, you'll be attacked by various gunmen, tanks and military aircrafts. Once your tank is badly damaged, bail! You might get on the second airplane but it got hit. So you have to dive down into the last tank, ending the skydiving sequence.

The cutscene shows a protestor got knocked down by a tank and an airplane with dangerous chemicals, turning normal civilians into zombies. Yes, zombies! Just hope you remember to by a car repair shop prior to the next mission. Or the zombies might overwhelm you and your ally when you come back to that place in the small central island with a few bridges lifted up to avoid a zombie catastrophe.

A Remote Chance
You want to get Killbane but his competitors are in the way. So you'll be in the helicopter with the improved RC Processor, capable of controlling any vehicle within range. The first is control the car by running down pedestrians. Second is the speed boat into the beach of party goers. Third is the helicopter to helicopter crash. Last is using a number of STAG tanks to take care of one moving tank with the wrestler in it. That would open a chance for you and Angel to wrestle him in the next few missions.

Zombie Attack
As a quick spoiler, the mayor is none other than Burt Reynold himself. Star in Miami Vice series and starring alongside Jackie Chan in Cannonball and its sequel. To keep it short, go to where the bridge has been lifted where the island of zombies were.

You'll be wearing a gas mask and even if you got unlimited sprint, your sprint will be limited so use it wisely. Take care and hold on to the sonic boom until all large canisters have sunk into the sea. The first is near the bridge on the right. Then go help Viola with the blue target. Then continue to the second canister but watch out for the brute! Then you and Viola head to the car repair area to get new gas masks. Remember to buy it before or you'll be forced to protect Viola for a limited time. If you did buy it, your guards will do the shooting for you. The last canister is behind the fence that can be open so you need to co-ordinate where you use the sonic boom weapon.

Now that it's done, you can change to any weapon. Also, using other weapons to shoot the canister would be an instant fail. Anyway, go to the truck that's marked on your minimap. Then you can either go over the bridge for Oleg, so you can have your army of zombies, or sink it to get Reynold himself and have your own squad that's more effective than your zombie. Now that's worth getting.
