I would be absolutely thrilled to play this game a whole helluva lot if only two things would change. First, the lag spikes are way too frequent to provide any kind of fluent game play. Second, the soul pick ups fade away over time - they probably should be instantly awarded on the kill, but if you need them to be on the ground a time before they are transferred to inventory make sure they can't be lost because a swarm of zombies decides to mass over them.
