You exit your apartment building only to find that there is a sinister silence in your area and unknown enemies. Get through the decrepit buildings and make your way to the rebels.
In short, the demo that I played was short and sweet.
A few things I had problems with, however:
The hints aren't needed. Most people who play these mods have a brain and can think logically. These hints are, like I said once again, not needed.
Second thing - I understand you are not English, but you have to get someone who knows English well to proofread the texts you write. The part with the 'Medic Man' had me cringing, to be honest.
In short, it's got great potential and I am curious as to when the full thing gets released.
