Rico was unrealistic with the huge ass chaingun and the girl was a overpowered sneaky mgs type of person with a silencer and a knife. I don't think it matters that they changed it up a bit. Went for some more balanced.

Killzone 2 = winter killer

I like the Sniper!

i hope i can always be a helghast.

they are so badass :D

medic isn't overpowered

in the beta I always got the most points as a medic, but that didn't mean they were overpowered by any means.  Just means that I healed people even when they didn't need it to get points.  All medics really sucks to play with.  But, that's co-op anyway so balancing is less important.

no cheap rewards for doing well, nope...the airbot can be summoned anywhere outdoors and will wander around the area it's spawned from shooting at people. You can only have 1 out at a time and there's a cooldown period to bring it back or reposition it. Airbots are a secondary ability, too, so once you complete a certain goal...I think it's just bringing one out...other classes can use it.

Turrets you can have 3 at a time and there's a similar cooldown. It's sometimes useful to suicide so the cooldown goes away because your turret stays when you die. I believe the airbot does as well.

yeah, you can kill anyonthing by yourself with a medic, but it will take you forever.  it's much faster playing with all 3 classes, and spec ops can give you grenades and shotgun ammo as well.
