- Martian Lander
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.

- Red Faction references
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.

- Easy sledgehammer kills
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 begin coming in through the holes. Take out the sledgehammer and hit them with it. If they begin 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 sequentially. Keep doing this until you have killed enough EDF. Notice: Do not go into the Chemical Depot.

- Fast vehicle repairs
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.
