This is one of my favorite Z-stomps ever, All the levels and episodes are laid out perfectly and there is always satifaction wit throwing a grenade into one of the zombie walls and watching the fall.
The only problem is that there were only four episodes and i finished them all in a total time of 8 hours (Not in one go) and im not willing to pay $19.99 for the GOTY edition.
Overall a really fun game if you want to continously kill zombies with freinds. 8/10
