Red Faction: Guerrilla

Story Related, Cannot be missed

The first two missions are already unlocked but to get the other three you will have to reduce/remove the EDF control over this Sector.
 
Rallying Point:
 
This mission sees you trying to prevent a peace rally from turning into a massacre. When you reach the place where the rally is taking place, you will have to wipe out the EDF forces that have arrived. After clearing out the EDF you will be told to destroy 4 PA Speakers, these are easily destroyed with either the Rocket Launcher or the Remote Charges. Your final task is to take down Colonel Halmark Gunnerson who was responsible for the attempted massacre. Stopping him is easy, just drive a big heavy vehicle into the path of his Armoured Car, then destroy it either with the Rocket Launcher or your remote charges. If/when he gets out of the Armoured Car, then hit him with the Sledgehammer. The mission will end once he's dead.
 
Ultor Echo:
 
For this mission you have to follow a Marauder vehicle and try to find the location of a stolen Red Faction Arms Cache. Once you get within sight of the target vehicle, you must stay outside of the red circle that's on your Minimap, else the Marauder will see you and you will fail the mission if you don't back off. Eventually an event will happen that will cause you to lose track of the vehicle so head towards the objective that's on your Minimap. Once you get within sight of the objective, you will have to exit your vehicle and move in on foot as the passage in front of you is too narrow for vehicles.
 
This next section is tricky as your map will be jammed so you will be blind for a while. All you can do is keep walking around and destroy the occasional wall so you can move forward. Eventually you will enter a room with a strange device in the middle of the room. Walk up to it, stand in the glowing circle and press to pick up the artefact. Now you have to retrace your steps and get out of there as the EDF are swarming all over your position. Once you've found your vehicle, drive away as fast as you can and head to the objective that's marked on your map. After arriving there, go to where Sam is standing and give her the artefact. After the ensuing cutscene, you will be at the Dust's Northern most Safehouse. Now is the time to buy and upgrade the Rocket Launcher if you haven't already.
 
Industrial Revolution:
 
If you've played the demo for this game, then you will remember this mission. The basic idea is the EDF have confiscated every Walker (Mech) in the Sector so the Red Faction is going to steal them back, starting with the one at a nearby base. Getting in to the base is easy, just grab a truck and plough straight through it and into the building where the Walker is being held. Once inside, enter the Walker and then plough through the base again towards where the objective marker is pointing. Press to get the Walker on to the back of the waiting truck. From here on in, the game becomes an on-rails shooter so just shoot anything and everything that shoots back.
 
Eventually you will reach a bridge which will promptly blow up once you cross it, thus ending the mission.
 
Ashes To Ashes (Liberation mission):
 
This mission is a race against an invisible clock as you have to save key RF personnel, data and supplies in the town of Dust from an impending EDF Artillery Strike so get over there and fast! Once you hit the outskirts the Artillery Strike will have already started so you won't have much time to play with. To save people you just have to go up to them and they will immediately run off, there is one person though in the town jail so use your Sledgehammer to break down the cell door. To save the supplies and data, just press when prompted.
 
For the second set of objectives, we advise you go for the ones in the bottom right-hand corner of the map as they're nearer. The data in the middle building is on the second floor. There are Marauders in the area so watch out.
 
In the final two buildings, you will find the last two people that need rescuing, the second of which is on the second floor of the second building. For the final part of this mission, head towards the objective marker on your map. The mission will end there and the trophy will pop after the ensuing cutscene.
