Just finished Rage a few minutes ago. Played it a Hard difficulty and felt it was too easy.
When I could snipe, of course I'm gonna snipe. That did cost me money at the store for sniper rifle ammo. If the mobs get shot in the head, they will always stick their head out a second time. Kinda ruins it. Wish they had been a little smarter. Mobs should get sniper rifles too. I did like how they would use grenades.
Don't think I'll play through it again. Tired of invisible walls.
