This game is so much fun! I would have given this five stars in total, but I noticed that in regards to time trial objectives, when the scene starts there is already five seconds on the clock. It makes things difficult in regards to the shorter time given on the larger population, Nuuk City for example and its 30 second all-kill objective of 125 kills. Otherwise, everything about this game is amazing!
Very well done game play
I enjoyed playing this game. the variety of upgrades, the different zombies, and four supports items are very unique and can be great if used in combination. This was a good sequel to the original. the only reason it's not 5 stars is because not all special zombies are available here. But nonetheless, a great game. PS. destroyed all cities in less than a year (232 days :P)
This game is one of my favourite iOS games ever. And the art... The PIXEL ART, just awesome.
