Terrible game with no way to repair your broken car parts (beyond selling out your friends or paying money that is). 1/5 for being a useless waste of time.
If the kerosine doesn't work on the house you need to talk to the observer again and get a quest to burn the house down first. It's not in the walkthrough.
Navigation is counterintuitive and non-logical.
knox1138, chosen one badge is 150 days. The hardcore version is 80 days.
Managed to achieve all hardcore items with a group consisting of 3 bowguns + 1 gravity gun ("rampaging ball of victory"). The second hardcore museum item will start you with a free gravity gun, and you need to make it 40 days to get that.
The number of kills in the game appears to be somewhat random, I get numbers like 161, 165 etc by the time I face the final boss, never been 169 yet....
