Arclegger just posted a question on Twitter about what kind of cover we prefer.
"Which crouch height cover would YOU rather have. Crouch and be able to shoot over (no protection from headshots) OR be covered completely." He does point out that PS2 will have both types.

Personally, I liked the stacks of 3 crates that you found on the walls in PS1 where if you were standing in the middle, you had partial cover and could fire. If you were crouched in the middle, you had full cover but could not fire. And if you were crouched on the sides, you had partial cover and could fire. What would you guys prefer?
