In order to unlock a weapon, you need to start a level that has that weapon in it, find that weapon, and finish the level with it. Simulations such as the level 0 are an exception; you don't get to keep the weapons, because they are not real. The following list is most unlockable weapons, the type of weapon, and the amount of carrying capacity that it takes up. In the second column is the mission that the weapon first appears in. The viblade is in the room with all the laser tripwires, on a stand in the center. The M60 can be taken from a guard when you fail to get let in by the front gate guard:

Oh, and sniper take up 3 inventory spaces, making them unwieldy, but the jackal and shockwave can be found in rooftops escape, and bridge assault respectively.

You may stick mines onto enemies or any other object, thus blowing it up. To do this, walk up to the object or enemy by pressing R (primary fire).

Once one player has gotten a weapon that another desires, go to Club:Stakeout on Agent. Drop that player's weapon to a second player. Have any one of those players continue through the level normally. If done correctly, the new player could have the weapons in less than three minutes. The faster way through the level is to run in the club after the first objective is complete unarmed, and rush to the very top to Jack Dark.

When the final Boss shoots plasma balls at you, simply move out of the way. When he teleports onto your platform and starts running at you with the sword, just dive roll out of the way immediately before he swings the sword. This will save you from receiving a lot of damage.

When the final Boss jumps to the platform you are standing on, he will lunge at you with his sword. Immediately before he swings it, dive out of the way. If done successfully, he will trip and fall. Quickly, before he gets up, grab his sword from the ground next to him and start attacking him with it. Note: The sword can be used to hit three consecutive times by quickly pressing R(3). If he manages to get away, he will summon his sword back to him. After this happens, simply wait for him to jump back onto your platform and repeat the process.

In a capture the flag game, have one player get the flag and bring it back to his base to score. Before he scores, have the party leader go to the enemy base and stand on the enemy flag holder (the colored circle under where the flag starts) and stand over it in a position so he can see the color on every part inside of the circle. Once he is positioned, score the flag and stay there. Every time you score it should say at the bottom, "enemy flag returned" After that, the flag will come back out as though you dropped it before you made it to the scoring spot. If you stand there, the flag will score very quickly but you will not be able to tell until the round is over and it shows the scores at the end of the round. If the player on the enemy flag holder dies or moves too far away for any reason, the flag will come back to the enemy base.

If you are a type of person who realy gets anoyed when you fall and die from a heigh place, read on. When you walk of a edge, quickly try to press the Left Bumber button so your player will roll and then hit the floor with no damage at all. Be carefull at your timing of pressing the button because sometimes the person doesn't realy roll when you press it.

During a game of Capture The Flag from the perspective of the team starting at Lion Temple Ruins, it is possible to position a hovercraft such that it barricades the main entrance to the enemy base at Sanctuary Caves, preventing the opposing team from vacating through this passageway. Enemies within this area are likely to open fire in an attempt to destroy the hovercraft. Make sure to bail out before it explodes. While they are preoccupied repairing the hovercraft, provided that it remains in place, this will afford your team a useful amount of time to grab the flag and make a successful getaway. This tactic is most effective when your team has gained control of each teleporter, forcing the opposing team to respawn within their base.

If you are in a small room and notice that an enemy is attacking you, switch to hand to hand combat. You will run a lot faster than they can. When you get close enough, press RB. You will steel your enemy's weapon or just knock it out of their hands. Your enemy usually relies on his weapon to kill you, and you can now finish him off with his gun or one of your own. Be careful though; an experienced player will do the same attack, and if your enemy is trained in hand to hand combat you will have a tough time defeating them because they will run faster than you. Also, they might have a secondary weapon This does not work if your opponent has two guns such as the UGL; you will only steal one UGL if you smack your enemy with this move.

While in cover mode and standing, move the crosshairs up to the very top then over towards you. You will be able to see more of what is on the other side of the cover that you could not see before.

Once one player has gotten a weapon that another desires, go to Club:Stakeout on Agent. Drop that player's weapon to a second player. Have any one of those players continue through the level normally. If done correctly, the new player could have the weapons in less than three minutes. The faster way through the level is to run in the club after the first objective is complete unarmed, and rush to the very top to Jack Dark.

Pick up a plasma gun then get into the hovercraft's turret. While shooting the turret, press Y as fast as possible. If done correctly, you will have a fast shooting plasma turret.

If you have a plasma gun or rocket launcher, get on the gunner position on a hovercraft and press Y once to swap it with the M60. You will now have unlimited ammunition for whichever you choose to put on the hovercraft. This trick can also be used to get a free M60 on a level that does not normally have one.

This can also work in multi-player mode as well. Get a hovercraft. Find a rocket launcher. Equip the M60 and the rocket launcher will be a rocket turret. If you play Mission 06 River Extraction under the Secret Agent or higher difficulty setting, you should be told by Jack to get the rocket launcher. Use stealth weapons at far range distances to avoid dying from the rocket launcher turret.

Go to the front of the base. Go to the left and go up the stairs. Then, turn left again and take another set of stairs. You will walk through a small maze of walls, but will reach the same point. When you are outside, go next to the tires. Make sure you have a Jakal, as other guns are not as precise. Aim at the main road and wait for an enemy. Most people do not know that a sniper will be looking for them and you can easily take them out with head shots. This spot is also good because on your left from the road, you have a view of another main road used in the level. If u are playing against more than six players, do not use this spot. Snipers from the other side will be posted and you can get killed from behind if your base is overrun.

When the final Boss shoots plasma balls at you, simply move out of the way. When he teleports onto your platform and starts running at you with the sword, just dive roll out of the way immediately before he swings the sword. This will save you from receiving a lot of damage.

This trick requires a Locktopus. To the right of the bridge are stairs. Go up until you reach the top. Then, go up to the ladder and pick the lock. This will give you a great sniping location, and you can bypass the enemies.

Get to the second level of the stage. When you enter the corridor that has the two traps, instead of continuing past the traps, turn around and enter the door behind you. Inside there should be two guards. On a crate near one of the guards should be the X-ray goggles.

Before the mission, select the demolition kit from the weapons menu. During the mission, after you kill the two brothers go across the bridge towards the rocket. When you get to the rocket, take a left and go down that road. When you get to the end of the road, there should be two doors (one on the left and another on the right). If you try to open them, they will say "secured." If you go on to a ramp that is on the right side of the left door, there will be a crack in the wall. Use the demolition kit to blow up the crack to get into the door.

On the level Trinity/Infiltration, leave the hangar after killing The Brothers. Obtain a sniper rifle from one of the snipers in the area, then head towards the gigantic rocket in the middle of the complex. Go to the circular rail around the bottom of the rocket, and zoom in on the blackened blast shield under the rocket engines. You will see a dead rat right in the middle, with eyes and little fuzzy feet. Shoot it for a bloody surprise.

When you are creating a deathmatch game with bots, look at the names of some of the bots. There are references to other Rare games. For example, "BOT-GRUNTILDA" is the witch from Banjo-Kazooie.

The Temple level has a similar design to the final level in GoldenEye 007 (also a Rare game) on the Nintendo 64.
