Just bought this game during the Steam sale, I was wondering if people who have played it could give me some early game tips?

Good luck with your first playthrough.

• Switch between your crew members often (favoring the 'talented' people) because someone will most likely die and you can continue the game as another character.
• Ammo is pretty scarce in the beginning (and guns without silencers are bad for stealth) so keep a couple melee weapons handy in your inventory. Storing the weapons in your stash will repair them (it might require tools).
• If you empty a house of all the resources it is cleared and no resources will respawn there. However some other resource might show up there if you leave resources behind.
• I think your camp still uses resources following real life time so you might need to check on them daily.
• There is a finite amount of tool resources so save some for a second base with more build slots rather than spending it on upgrading your first base.
• Don't stray to far from vehicles and keep an eye on your minimap for 'special' zombies.

@thesquarepear: I have a question regarding looting materials. Is it better to take the rucksack or to break them open?
