When you enter the room immediately after you use the jet to transport Gryphon go to the center room you will see a huge Modulation Droid. Run and dodge the bullets and missiles. Look around the room to find ladders all around leading to the top of the ceiling. Climb the ladders and get to the top. Then, look around to find boxes all around. Go to the boxes and walk into each of them on every side. You will get a lot of ammunition, health, and Enviro-suit repair kits. This should prepare you for the Modulation Droid.

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

When Hendrix first starts talking to you, go down the catwalk away from the APC. There should be a tunnel that leads to a miner and guard fighting. Shoot that guard then shoot the one at the elevator. Stand in front of the elevator and face the wall behind it. Look up slightly to see a hole. Enter the hole and at the end is a pond or lake. At the bottom of the pond is a miner's body, health, and an Environment Suit.

Suggestion: Saving ammunition:
When you have remote explosives, do not use up ammo for your other weapons. It only takes one to a few remote explosives to take out enemies. When you start the game and get to the part where you see the four troopers and the enemy APC, throw a bomb down by the APC. Detonate it and the bomb will blow a huge hole in the ground. If done correctly, the APC will fall in and explode when it hits bottom. Take advantage of the geo-modification of this game. This also works with groups of enemy soldiers.

If you are low on ammo in any level and do not have enough bullets to kill an enemy, press Up to aim carefully, then shoot an opponent in the head. They will automatically die in one shot, saving ammunition.

Suggestion: 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.

Suggestion: Feeding Area: Reach next level:
When walking through the Feeding Area, go to the edge of the cliff. Look down and you will see ice. You will not be able to jump down. However, blow another hole in the ice closest to the edge, and then jump off. You will be in the water and in the next level.

Suggestion: Lobby: Secret roof area:
Go to the second level of the Lobby multi-player level and grab the rocket launcher. Walk over to the edge of the balcony and start shooting up towards the wall facing the lobby itself. After enough shots you will dig a tunnel to the roof. Walk through and jump right up. You can shoot out the glass and snipe people down on the second level. There also is a Fusion Rocket Launcher that you can grab.

Suggestion: Lobby: Hidden items:
Go to the four corners on the first level of the lobby after you have obtained the rocket launcher in the muti-player level. Use the rocket launcher on the four corners to find health, enviorsuits, a fusionrocket, a flame thrower, and a rail driver.

Suggestion: Mercs Base: Entering:
After the crash site, you will follow a system of tunnels and ridges filled with enemies (most with heavy machine guns, some with fusion rockets and rail drivers). When you meet the Red Faction miner in the caves, he will say that he will watch your back. At this time you will follow a tall tunnel to a bridge -- you do not want to be on the bridge. Between the miner and the bridge is a turn off that leads to a catwalk going over the bridge. Kill the two gaurds and follow the catwalk until it stops at a hole in the wall. Jump from the catwalk into the hole and follow it until you get the grenades. Use them to kill the turrets and the fusion rocket carrying guard on the other side of the large rock by the grenades. This saves time and health you would have spent trying to fight the guard and the turrets.

Suggestion: The Shooting Gallery: Avoiding damage:
When nearing the end of the game in single player mode, you will have to catch the tram to proceed to the next area. The tram is located immediately after "The Shooting Gallery." In order to avoid fighting most of the guards, equip the Heavy Machine Gun. Next, proceed down the track towards the small door to the left. Inside, kill the guard. Once the other guards stop rushing in and shooting at you, collect the health vial (just behind the desk), dash out of the room, head towards the front right side corner of the train, and duck down immediately. This will prevent gun fire from hitting your character. Stay ducked down until the loading screen appears.

Suggestion: Roof: Secret area:
Get up to the roof easily by looking for the side with a slant. On the second level, shoot about three to four shots to the wall next to the slant. Once on the roof, find the area with the glass. Get to the back wall so you are looking at the glass, where it slants, then run at it. As soon as you hit the slant, jump. This is difficult to accomplish. However, when you are up, you can jump from the top to the small bridge-like place on the side. Make sure you do not stand on the glass to avoid someone shooting it and causing you to fall. From this height you will lose about sixty health from dropping off.

Suggestion: Warlords: Suicide hole and sniper:
Get on top of the roof of a bunker (where the fusion rocket launcher is located). Start blowing out holes in the wall in front, so you can get in. Keep taking out the wall with your mini-rocket launcher at a slant. After a while, you can turn right with your gun and take out the wall so you can see the light -- this takes some time. After you can see the light, look down. Usually you are high up. Jump off to make your self road kill, or take a sniper rifle up and take out opposing players. You can get so high up, that when you look up from the ground the hole will actually be over the cliff and not even on the level. If you get up this high, you can see the map plus cloud-like objects. Do not fall down or you will go into an eternal fall. When this high, your guns will have unlimited ammunition -- hold the fire button to see your gun fire a lot.

Suggestion: Waste Disposal: Easy kills:
In multi-player mode on the Waste Disposal level, swim down under the platform to find a fusion rocket. You can also use mines to blow holes under the doors into the hallway. When bots come by, they will fall into the water for an easy kill.

Suggestion: Multi-player mode: Extra characters:
Successfully complete training mode to unlock extra characters for multi-player mode.

Suggestion: Secret fishing holes:
When you first start a new game, go to the first hole on your left and go to the end of it. There will be a small hole where you will be able to see into. Go forward in the game and get a rocket launcher or mines and return. You will be able to get in the hole, swim, and shoot the fish down inside.

Go out over the pit where there is a group of guards and the tank that will shoot at you if you do not blow up the bridge. Go down the tunnel and it will lead to a open area, where after you kill all the guards, an elevator will come down. Immediately above the elevator is hole that is difficult to see. Go left of the elevator, go up the hill, and go into the hole. It will lead you around until you get to a large open room with a lot of water with fish, bats flying around the roof, plants on the wall, and a dead miner at the bottom (where there will also be Extra Life and Extra Body Armor).

Suggestion: Destroying turrets:
Equip remote mines or a rocket launcher. Then, use heat seeking mode to lock on to the turret. Fire away and blast the turret easily. Note: If you are low on rockets and have remote mines, then use them on ceiling turrets.

Suggestion: Defeating Masako :
Masako has some nasty weapons and a shield. The only weapon that can defeat her is the powerful assault rifle. She first attacks with a ship firing rockets and machine guns. Equip the laser to blow it up in one shot. Then Masako herself appears with a shield, just like Capek. However, she uses a precision rifle very fast. Keep moving and destroy her shield with your rifle. Then, keep your rifle armed to kill her. Take her Precision Rounds after she has been defeated.

Try to get higher than her. Hit her with three Fusion Rockets to disable her shield. After her shield is no longer working, she will hide under a ledge. Use a Rail Driver to her head for a easy kill.

Suggestion: Secret sub bay:
When you first get the sub, take it down through the tunnel until you exit into the cavern. Look along the wall to your left to find a small crack, that at the correct angle, you can see another tunnel. Yse your torpedoes and break apart the wall around the crack. You will now be able to follow a tunnel that leads to a cave (with bones lying on the ground), and a brand new sub with full health and full ammunition sitting in the middle of a small pond.

Suggestion: Secret areas:
Immediately after Parker pops Capek's nano-tech shield (during an intermission sequence), you will follow a trail. When you reach the area where a dead guard is on the ground, look to the right. Note the small hole where it looks as though a small animal could fit through. Get an explosive and blow a hole big enough to fit through. Enter it to reach a room. Jump to the center then jump up and down to get a fuel canister and fusion rocket launcher.

When you enter the room immediately after you use the jet to transport Gryphon go to the center room you will see a huge Modulation Droid. Run and dodge the bullets and missiles. Look around the room to find ladders all around leading to the top of the ceiling. Climb the ladders and get to the top. Then, look around to find boxes all around. Go to the boxes and walk into each of them on every side. You will get a lot of ammunition, health, and Enviro-suit repair kits. This should prepare you for the Modulation Droid.

Suggestion: Finding secret areas:
Every time you see markings on the wall (for example, posters and paint) in multi-player mode, use something explosive on it. It will lead to a secret area.

Suggestion: Sniper rifle:
Immediately before the abandoned mines is an elevator that goes down toward the abandoned mines. When you go down there, you will find a ladder next to you. When the elevator stops, before it hits the bottom of the pit, grab the ladder and climb up until you reach a hole with some bushes in it. Enter the hole to find a Sniper Rifle and some bullets.

Suggestion: 100% accuracy:
To get 100% accuracy with any gun, including the heavy machine gun, just hold the D-pad up to aim. When you shoot, the bullets will always hit their mark, even if you hold down the shoot button with an automatic gun.

Game Flaws: Guard suicide:
When a new game is started, you would usually follow a fellow miner, hear them talk, and then fight each other. Instead of listening to them talk, go right past them. One of the soldiers will start firing at you. Immediately after he starts firing, place your fellow miner in between yourself and the firing guard. Your fellow miner will die, leaving the guard he was talking to start talking to himself, fighting himself, and then killing himself.

Game Flaws: Free Fusion Rocket Launcher ammunition in multi-player mode:
Once you have the Fusion Rocket Launcher in multi-player mode, kill yourself with it, If you can get back to your corpse, you can pick it back up. When you do, it will have three shots on reserve and a fourth ready to fire.

Game Flaws: Water in the sub:
In training mode, after you ride in the submarine, point the nose of the sub out of the water. Make the sub completely vertical, then press X to get out. You will get out of the sub in the cockpit of the sub. You can look outside, and there is a bit of water in the sub where the chair is located.

Game Flaws: Remote charge on sub window:
When you have remote charges, get a sub. Stay outside and throw one directly on the window. Get in and there will be a remote charge on the window.

Game Flaws: No gun:
When in the areas before Capek, you will notice that sometimes there will be bathrooms. Go in and look to find mirrors. When you look at one with your gun out, you may notice you have no gun. To really figure this out, look to the side so you can see the mirror out of the corner of the screen, and your man will not have a gun. If you pick up a body and look in, you will also notice you do not have a body on your shoulder, just air.

Game Flaws: Trap enemies:
In the Fortress level, get to the top of one of the fortresses. Aim the rocket launcher at the bottom of the other base. Hold the secondary button. After the cross-hairs turn red, release the button. The rocket will fire and will begin homing in on an enemy. If done correctly, the enemy will be running into the enemy base, the rocket will not be going at a steep enough angle, and it will hit the ground creating a hole. After you have created the hole, can use the primary fire on the rocket launcher to burrow and make a pit. CPU enemies will fall in and appear to be running. If multiple enemies fall in, they will shoot at each other but rarely hit, even if they are on impossible level. Use the flame thrower, flame some of them, and this will usually kill all who fall in. That is the only way to burrow into the ground in that level.

Game Flaws: Enter and walk around the driller:
When you find the driller and get inside it, drive it out until you can get out and walk around to the back. When facing the back, jump up onto the back of driller. This may require several attempts. You will then be able to walk around on top of the driller, but half of you will be inside it. Keep moving around on the top until you fall in. You will now be able to walk around inside the shell of the driller. To get back out, go toward the front and press X to drive it then press X again and you will appear back outside of the driller.
