This film is entirely devoid of any plot, character develoment, or even noticable script. Its a giat plot hole held together with a series of game cover art shots of hot girls shooting shit while stuff blows up.
Do not go this film for interlectual stimulation, there is none!
I give it 9/10 and a I particularly liked the steampunk zombie German soldiers (WWI so just German soldiers, not zombie Nazis which is somethign else).
This is called entertainment so go and be entertained.
