From the Store description:
VirusInfection is a survival FPS, a true FPS , where you can walk or run in the street, jump, destroy windows, pick up ammo.
Your goal is to survive as long as possible in the streets of an abandoned city, infected with a virus after military research.
For this you have several weapons, gun, AK47, sniper, MP5, shotgun.
What's remarkable about this title is the 3D world and speed with which you can move around and look. Running, walking, jumping, picking up ammo or health packs, shooting zombies (of course), the modelling of the world is hyper realistic. You can look up and down as well, showing proper perspective, while the audio is modelled well and the noise of your chopper on the roof of the main building varies according to distance and height.
The developer knows full well that this is just the start, promising in the Store text:
Coming soon :
Also missing at the moment is any kind of monetisation or IAPs, so have a blast, think of this as a playable demo, and go from there....
Not bad at all, though horribly unfinished. One to watch in the Store!
