What are your favourite weapons?

For me the ripper and the line gun... they render the harder jobs easy.

And for you?

I used the starting gun (forget the name) the most.  Flame thrower was pretty cool though.

force cannon - fully upgraded. Found it useful in every fight.
plasma cutter for longer ranged combat.

I am going for the Plasma Cutter trophy now but the force cannon was really my favorite one.

Plasma cutter was definitely my favorite. Plenty of cheap ammo, and fully upgraded can slice and dice those necromorphs.
 
You could even cut a tin can with it.

I'm gonna go with the line cutter. I thought it was totally awesome. The plasma cutter was great too and I really enjoyed how you could switch it's aim between horizontal and vertical.
