Could have been great
You better get used to this sound of your character's footsteps if you intend to play this game, as you're going to hear it for a long, long time.
This came pretty close to being a really good game - clearly a lot of time and effort has gone into making it. The title screen and game environment have all been lovingly drawn, and the background music is pretty ominous. The introduction sets up a sense of promise and expectation - a soldier's troop has been attacked, your character has woken alone, and "needs to find some answers". However, this is when it seems to go a little wrong. Unfortunately, after playing it for a long time, I still didn't have "any answers"!
The game consists of walking around, shooting zombies and other monsters, whilst trying to access cards to open up other areas of the game. However, the game map is very large and your character doesn't appear to run. Together, this means that it takes a very, very long time to get anywhere. Additionally, there aren't that many zombies, so unfortunately you spend most of your time just walking from A to B (Tra-trudge....). When they do show up, they aren't that hard to gun down, so it's back to walking again (Tra-trudge).
If you've get some time to spare, it is worth a look, but be prepared to spend a lot of that time walking around, wondering what you really are supposed to be doing!
Possible improvements would be to speed up the gameplay a little - faster movement and faster zombies, and more enemies would definitely help spice this up.
It's a real shame, this game had some serious potential, but unfortunately just doesn't quite deliver.
