How do I beat a beserker?
The beserker is one of the toughest enemies I’ve run into while playing gears of war 3. If you find yourself fighting a beserker you’ll notice that bullets don’t really seem to do much. Beserkers normally come out on the “Boss” waves which are 10, 20, 30, 40 and 50. To beat a beserker you need a flame thrower. Hitting a beserker with flame will greatly reduce its mobility and reduce its defenses. When hitting it with a flame thrower your teammates may be able to shoot at it at the same time with their regular weapons. Slow it down with a flame thrower and fill it full of bullets and you should be able to beat it without too much trouble.
You’ll also notice a pattern with the beserker. It will square its shoulders to you and will run at you (and run through small obstacles). Make sure you jump to the side when it squares up with you and starts to charge. The beserker has pretty poor eyesight (which you’ll notice if you use it in Beast Mode). Staying back may improve your chances of not being seen by the beserker as well.
Good luck!
