I remember I really liked the first episode, but I can't say the same for this. Basically, the "free runs" into the sky/space are meant only to unlock missions and earn money. The only important thing here is doing the missions. And I don't like that.
Bots are useless, with some weapons they hardly fire at all... which makes my character extremely vulnerable. Aiming is also a NO-NO: I fired with the hunting rifle against an "army" zombie-soldier in the head 5 times but no hit.
