To easily get fast-forward to work without ruining your trigger finger, do the following: Hold RT and press START. Then let go of RT and press START again. Now it will fast forward automatically.

You can only do this when you're playing offline. Lower your weapon by holding down "Grenade Switch" + "Reload" + Click the Right Stick + Down on the D-Pad. That would be B + X + CLICK RIGHT STICK + DOWN (D-Pad) on the default controls, but this also works if you have different control settings!

To take less damage when falling, you can try to crouch just before you land - it's all in the timing - and it can make it so you don't take as much damage when you hit the ground.

Unlock REACH RACER Easter Egg

When you're in mission 03 (Oni: Sword Base) there are two hidden switches that look like "doors" that you can open only with both players in a Co-op Match. Both can be found after Rally Point Alpha where you must destroy the wraiths. Switch A is on the coast of the water a little southeast from the buildings with a pair switches you must activate. It is on a pile of rocks near the big frozen waterfall. You'll know you are standing in the right place when you get a message saying "Hold X to Open Door." You must reload your weapon before getting to this point. Switch B is just past the AA cannon in the next area. A pile of rocks with some trees on it overlooks the big walled complex on the ice below that area. With both players standing in these places, press X simultaneously (at the same time) and a message will appear on screen saying "REACH RACER" You will then be warped to the Oni: Sword Base with two Gauss Cannon Wart Hogs ready for racing. The race course is marked with red waypoints. The loser's warthog blows up and you can start again!

You can use this trick from Halo 2 - to get faster melee attacks: Pres RB and then quick press X and RB together. This should make you hit faster.

On the level when you fly around the city in a falcon. When kat needs back up on oni base and only at this time go to the club and go to left of the club and there will big a little opening. There is a button on top op this opening you need two people on needs a jetpack an you fly up there. When you click the you got to the ring and fly in the middle of it and it turns into and it is a plecan. You can do this with a banshee and you do the same thing its a phamton

If you want to rank up fast, try this:
Do firefight on legendary.
Put the overshields on x4 and the power on invincible, the damage on 300% and choose weapons you like. Put the ammo on bottomless cup.
Now make your own waves. Put (almost) all on either elites or brutes. You can't die so don't worry about hammers or feul rod cannons. If you don't have the killionaire achievement, put in one bonus wave full of grunts and choose an explosive weapon (plasma grenade launcher, feul rod cannon, rocketlauncher). Wait until the grunts jump out of the plane. When a big crowd of grunts have gathered, shoot your rocket a few times and you will easily get the achievement.

If you want to experience an awesome way to enjoy Forge World, then read the following text.
step 1: before starting the map, set the base player traits to 50% gravity, 300%speed, and 300% jump hight.
step 2: start the game of forge and spawn an EVADE armor ability (on a raised platform like the hanger) and spawn an incline at the edge of the platform.
step 3: Have someone pick up the EVADE and start running for the incline. Once you hit the base of the incline, use the armor ability.
CONGRATULATIONS, if you did it correctly, you should be soaring through the air faster than a banshee in full boost.
step 4: Have fun and tell your friends!

First what you have to do is set the map to Holdout. Set the difficulty to easy. Go to game options then spartan settings then Base traits then sheild and health. Set damage resistance to invulnerable. 4x sheilds. Set your damage to 300%. Put gravity to 50%. Jump height to 50%. then go back and go to loudouts. Put your 1st and 2nd weapon to DMR and Plasma Cannon. Your epuipment:jet pack. And 4x frags. Now you should rank up faster.

Iron Skull - Co-Op reverts to previous checkpoint on player death. Single player death restarts entire mission. (Restart at checkpoints with all of your weapons and ammo in co-op, but you'll restart the mission on single player)

Cloud Skull - Motion sensor disabled with this setting. (No "radar")
Famine Skull - Weapons drop 50% less ammo. (Less ammo from picked up weapons)
Thunderstorm Skull - Major upgrade to all enemies. (All enemies have more life)

Mythic Skull - Double enemy health. (More health for all enemies)
Secondary Skulls
Blind Skull - HUD and first person arms and weapon are hidden. (Clears the screen but won't affect gameplay)
Cowbell Skull - Acceleration scale from explosions is 3x. (Things fly further)
Grunt Birthday Skull - Grunts explode as if they were plasma grenades when they are killed with a headshot. (More explosions = more fun)
IWHBYD Skull - Common combat dialog becomes less common, and vice versa. (Hear rare dialog from computer-controlled players)
