There's no co-operative team dynamics here and it's not even related to a video game (as far I can tell) but Isolated manages to tickle many of the same places in my head that enjoyed the Left 4 Dead series. The slightly elongated body types, great animation and funny-yet-dark tone all make it a piece of zombie-centric entertainment that's a disembodied head and shoulders about lots of other stuff out there. Here's hoping there's more to come from these filmmakers.
