OK I am liking the quick menu more now I worked out how to assign the D-pad to weapons etc.
I have killed/completed the big guy with giant axe section!
Still not killed to chainsaw dude!
I'm sure the full game will provide you will more ammo/weapons/powerups. Demo seems to just dump you with bog standard equipment.
@ FKNetwork: Yes there is a screen tearing issue.
@ z101: Yes there is definitely a lack of atmosphere.
