It could be a good game, but the controls are just plain clumsy... I kept dying trying to switch to a certain piece and accidently moving a completely different one.
Maybe a bonus for killing stuff after you die? Most of those achievements reward upgrade points, which don't seem very useful if you are fully upgraded...
Would be nice if you could toggle Perception to put those arrows over the actual object on the road instead of having to look up top. Maybe even include the civilians in the perception. The only item of Perception in its current mode that was of any use was for the explosives.
