Gears of War Tips

Infinite grenades in Multiplayer mode
This trick can be done on any online level. First, get either smoke or frag grenades. Take out your Lancer and do an Active Reload then immediately switch to your grenades and press B when switching. Then, press RB(5) or RB(10), depending on the game. Next, throw your grenade. The ammo counter should read zero but you should be acting as if you are holding a grenade. Note: You can only tag people and if you switch weapons you will exit the glitch.

Hidden video
Turn on the game and wait for the "Gears Of War: Press Start" screen to appear. Do not press Start. Allow the screen to idle for a few of minutes, and a video will begin to play about Emergence Day.

Faster reload times
When you press RB to reload, there will be a clear bar with a small white segment somewhere along it. It will appear where your bullets used to be. There will also be a smaller white bar moving across the clear bar. As soon as the white bare gets inside the white segment, press RB again. This will reload your weapon much faster, and if timed just perfectly, will give your gun an extra boost in fire power. However, if you do not time it correctly, the clear bar will become red and it will take even longer to reload than if you had not attempted it.

About Face maneuver
This type of move is done when your character whips around 180 degrees quickly. To perform the move, hold Analog-stick Away to start walking backwards + A for a short time. Release A when your character turns around to perform it. To avoid frag grenades or retreat somewhere fast, keep holding A and Marcus will "roadie run" in the opposite direction.

Closing Emergence Holes
When an Emergence Hole opens up, toss a grenade into it. This will automatically close the hole, and therefore keep the locusts from coming out.

The Hammer Of Dawn can easily destroy Emergence Holes. You must activate it by targeting an enemy first, and then aim it toward the Emergence Hole.

Fire a Torque Bow arrow into an Emergence Hole. This is somewhat challenging to do, due to the straight line of fire given by the bow. However, if you are close enough to fire while the line of fire is arced, it is possible to make it into the hole. A Torque Arrow stuck in the top of the hole will close it as well.

When there is an Emergence Hole, take out your Lancer, go over the hole, and hold B. When you do this, every enemy that comes out of the hole will get chain-sawed.
