When your health is low during any mission, enter any vehicle for a few seconds. Once you get out of the vehicle, your health/shield will be completely healed. This works anytime, and you cannot die while getting into a vehicle.
Use the following trick to easily unlock the "Super Hammer" cheat, which requires 100 EDF kills with the sledgehammer. Go to Dust near the Chemical Depot that is by the Badlands. Kill a few guards, then go back out of the depot. Wait for cars to pass by, then take them from the civilians and guerrillas. Form a wall using these cars with only two openings just big enough for people to fit through. Wait for the EDF to start coming in through the holes. Take out the sledgehammer and hit them with it. If they start trying to bash the car wall, blow up their cars. You can use the sledgehammer, but it will take awhile. Try using the explosives because the kills do not have to be all in a row. Keep doing this until you have killed enough EDF. Note: Do not go into the Chemical Depot.
To repair any vehicle quickly, just use Guerrilla Express while inside your vehicle. The vehicle can now be found in or near the camp you traveled to, with no damage.
Exit a vehicle near the end of a mission. Successfully complete the mission, and return to the vehicle. It will be fully repaired.
If you hijack an EDF tank, you are unable to heal it by teleporting to a safehouse. In fact, the tank disappears. You are however able to heal tanks or any other vehicles by going to a demolitions master. Leave the area during the event, and you will fail. After the challenge ends, you should have a full health EDF tank where you left it before the challenge.
Exit a vehicle after it overturns. When it is on its roof, walk near it, and re-enter it. Repeatedly tap [Enter Vehicle], and the vehicle will turn over with its wheels back on the ground.
Purchase the satellite locator upgrade with recovered salvage at any safehouse. Get a vehicle, and start driving around. When you get within range of a radio tag, a small pulsing green dot will appear on your map. Follow the map. The green dot indicates the location of a missing tag. Some of the tags are in difficult to reach locations. Using a dune-buggy type vehicle is recommended.
Southeast of the Badlands safehouse near a large group of ore is what appears to be a Mars Exploration Rover. It is marked as a vehicle on the map, but cannot be controlled or destroyed.
If you kill your brother, Dan, at the very beginning of the first mission, you will die instantly, but the death message reads "WTF? You killed your brother?"
The area "Parker" of Mars is named after the protagonist in the original Red Faction. The area "Eos" of Mars is named after the Faction's leader in the original Red Faction.
When you are around people, they will sometimes say things about Ultor, which is the company from Saints Row 2. They will also say "Damn drones confiscated my Feed Dogs collection", which is the band from Saints Row 2.
The area "Mt. Vogel" of Mars is a reference to Dean Vogel, whom you had to kill in the last mission of Saints Row 2. You also only get to enter it during the last mission before the campaign is complete.
