great game
My only issue is the guns. Once you get the hunting rifle, that's your best bet because the uzi, M-16 and AK-47 are practically worthless, even as "back-ups" (the regular shotgun works fine)
But I do like the "secret" weapon you have after all the other weapons are found. As a famous actor once said.........
" IS NICE!"
As for the searching, could you explain how exactly you "search for weapons" or "search for survivors" as completely seperate actions? When you start looking all over town for guns, chances are you might stumble on people (and vice versa).
Rather, you should be able to just "search", and instead of just deciding HOW LONG, you should have to pick locations you think would have the stuff you need. It would also be more interesting if you added more dimensions like "food" and "defensive wall materials". Just my 2 cents.
