The $1.99 game puts you only seven days away from the end of the world as an unknown virus has started turning humans into zombies. The only hope is a Dr. Kayla Cupper who has discovered the source of the infection. Your job is to protect Cupper while she is able to develop a cure for the virus.
The game offers two modes: survival and history with either "bird's eye" or "back" camera views. Survival is your typical high-score last-longer game in which you are fighting back an endless stream of zombies and ghosts.
The history mode is perhaps more interesting with 7 distinct stages that represent days to the apocalypse. Each day involves accomplishing very specific goals. These include:
Day 1: The Beginning - You have to kill 25 zombies.
Day 2: Protect Cupper - You have to protect a Dr. Cupper from zombies as she (slowly) walks to the mansion.
Day 3: Infected - You have been infected. In this level your life is decreasing continuously, so your only option is kill as fast as possible, to get life items.
Day 4: BioHazard - You have to find some 10 Biohazard containers strewn across the yard
Day 5: Spectral Chaos - You have to kill 35 ghosts.
Day 6: Apocalypse - You have to survive a 5-minute onslaught.
Day 7: Last Hope - You have to protect Dr. Cupper again from zombies, as in level 2, but with more zombies and ghosts.
I actually found the history mode to be quite enjoyable, and felt the distinct goals made the game far more interesting. Trying to complete a specific level was much more of an incentive than simply starting up another survival match. The later levels also add a ghost enemy which can be harder to kill and requires some change in strategy to survive. While I was able to complete the history modes relatively quickly, others seem to be having some difficulty. Regardless, I felt the difficulty progression was a bit off as the 6th level seemed by far the hardest.
Developer's gameplay video:
In the end, the game successfully delivers what it promises: an effective 3D survival shooter with good controls -- and the game's 3D engine is nicely done. That said, there are a number of fairly obvious "1.0" deficiencies. No global high scores and no difficulty level options are perhaps the most needed to ensure ongoing replayability. Meanwhile, there have been a number of requests to expand the current weapon supply which is limited to only 3 distinct weapons.
While the game's likely worth the $1.99 in its current form, a few additional improvements could make this game become highly recommended.
