Gears of War/Tips

Reload Audio Cues
When you're firing (Lancer & Hammerburst at least)and your clip starts to run low, your gun will start to make a clicking noise with every shot, that way you know to keep your eye on the ammo and start planning for a reload

Auto-Reload Melee Trick
Sometimes during a firefight, you will inevitably stop watching your ammo level and an unexpected auto-reload will occur. If you're looking to keep your damage boost high using the active reload, this can be a real problem. The solution is to press the melee button if your active reload meter has already passed the small white zone. The reload will be canceled and as soon as you release the melee button, it will start over. This will allow you to pay more attention to the active reload meter. If your weapon isn't empty, it will just cancel the reload. However, there are 2 issues with this trick. First, it doesn't seem to work while you're taking damage and second, it will cause you to leave any cover you are behind. This isn't an issue if you are standing behind a wall, but it can be disastrous if you are crouched and it causes you to stand up.

Shotgun Roll
When faced with an enemy about 5 to 6 feet away who is about to kill you, pull out your shotgun and hold forward while pressing A to barrel roll into the enemy. As soon as you come out of the roll start shooting the shotgun. If your roll was straight you will be aligned perfectly for a one shot kill.

Grenade Tag
With fragmentation grenades equipped, sneak up behind an enemy and hit 'B'. Make sure you run away to a safe distance to watch them blow up.

Defending a Grenade Tag
When you see someone running up with grenades equipped, there is a way to take them out without them tagging you. Have your Lancer Rifle equipped, and as the grenader approaches hold B to keep the chainsaw revved. If they get too close, you will chainsaw them automatically before you are tagged. A very good tactic.

Skipping a cutscene
Press X in order to skip a cutscene. Scenes in-game cannot be skipped. e.g. the "we can take the safe route or go directly into action"-speech at the beginning.
