i thought they were like the coolest bosses so i would like to know if they will be in gears 2

Probably.

I thought they were a pretty awesome idea but I didn't like the execution.

The first one was pretty cool. You have to figure out what to do and it's just a lot of fun.

The second one was annoying because the game is telling you one thing and wanting you to do another. For some reason the satellite can't see through the bright glass so you have to break the pillars holding the glass up. It ends up just not being totally obvious and ruined that fight.

In the previous two fights they taught you to break things with the berserkers but in the third they decided to throw that out the window. Instead you're just supposed to run to one end of the train and then to the other. Lame.

I have beaten 1, and I thought it was a pretty good boos, though I dont understand how that thing can even withstand 1 does of that massive laser beam

Im betting there will be new beserkers, and maybe old ones.

 the third berserker you can also blow up the fuel tank

Yes, there's more than one way to kill the last berserker.

Unless rockstar takes over their going to be in there.

This is like asking if there will be Hunters in the next Halo game, or a Mummy in The Mummy.
