in the multiplayer mode choose the towers level. to get out of the tower just jump over the ledge, and to get back into the tower just go to the wall underneath it and press R1 + R2 + O + X (press this 3 time to make a door apear)


Easy kills
Throw a remote mine on an enemy. If it hits, they will scream and run around instead of shooting you. Let them run around and eventually they will try to find guards. When they do, detonate the bomb to get two or more frags for one.

Unlock everything
At the main menu, hold select and press left, right,up, down, circle, triangle, square, x. If you enter the code in correctly, the screen will turn blue.

Badlands: Bottom of level
In this level, there are natural bridges over a giant pit which if you fall, you will usually die. Use the following trick to get to the bottom without dying. This will be difficult if you have more than two bots. It is recommended that you try this alone first. Find the rocket launcher that is next to a bridge. Go on the bridge and face the flat wall that leads to the bottom. At a 45 degree angle, start blowing holes downwards until you have almost reached the bottom. You now have to jump and try to make it into the first hole you created. .You will lose some health here from the fall. Once you are there, go backwards out of the hole and slowly drop down to the next hole. Repeat this pattern until you get to the bottom. Save at least 1 rocket so you can kill yourself -- the bots will not be able to get to you. This is difficult to do when playing against bots because of them shooting at you. Set the timer to 30 minutes. Take a lot of weapons such as the Rail Driver and the Sniper Rifle with you. Start blowing up the natural bridges from the bottom. Do not do it completely, but just enough to watch all the bots plunge to their deaths.

Blasted Canyon: Sniper hole
You will start in one of the two blue boxes on the sides. Use a rocket launcher to tunnel down. Take about two shots in the back, then down about two to three shots. After that, just shoot out the walls in front (that the windows on the blue gate objects are) until you see light. Peek out and you can see the level below your box. Note: You may die a few times before accomplishing this. In multi-player mode, select the Blasted Canyon level. When the game starts, look out onto the field and turn right at the wall. Get a rocket launcher and begin blasting the wall. Soon it will be large enough for you too fit in. Get inside, look down, and shoot a rocket (killing yourself). When you go back in, you should be under the floor. Begin blasting out some of the rock under the floor (killing yourself in the process.) After awhile you will have a cave under the floor. If you wish to make a sniper point, blast (under the floor) towards the field. You will soon see light, in which case you should blast open more until you can see the field. Note: Always bring a rocket launcher down with you, in the event you get stuck there is no getting out.

Getting health
When low on energy, kill worker doctors and even Red Faction men to pick up more health and Environment Suits.

Avoid detection
In the single player game, there are two locations where you have to be stealthy. One is when you pretend you are a businessman and the other is when you have to pretend to be a scientist. To make it easier to avoid detection from guards or other pedestrians, always look down or away from people. No one will learn your identity until you look them in the face.

Installation XJ5: Hidden pit
In the deathmatch Installation XJ5, you can get outside to the pit. Grab the rocket launcher and jump down, then turn left. Note the archway above. Blast a hole in the wall below the doorway and start building a tunnel straight to the open window. Just going to the archway above and blasting around the window does not work due to an invisible wall. Once you make the tunnel all the way through, you can look down into the pit below, If you drop down, you will always die. Turn to the left or right and blast a hole big enough to jump into (make the hole on the outside of the wall). Jump into the hole, then make another hole directly in front of you but down slightly. Now that you have made another hole, jump into it. Make sure the hole is not too far down, or you will die from the fall. Repeat this process until you have reached the bottom of the pit. Note: It is next to impossible to get back up once you are down there.
