You started out in a subway. There was a train arriving now and then but i dont think you could get on it. There were neutral people walking around and also a cop. Shooting somebody made him hostile.

There was a small room to your right that held a gun and some ammo (possibly?) I remember you having a regular gun and some sort of pistol that shot electricity (think stun-gun)

Further ahead there were also a hospital in which you could heal yourself by walking over medkits. I think all people outside the subway were hostile.

I think i played it on some sort of demo-cd from an old computer magazine.
