We have a temporary work-around for the crash near the end of the game that win7 users. Go to your oneshot steam folder (should look something like "C:\Program Files (x86)\Steam\SteamApps\common\Oneshot" ) and find oneshot.exe. Right-click it and hit "Properties". Then go to the Compatibility tab in the Properties window, and set the program to run in Compatibility mode for "Windows Vista". This should let you progress through the end of the game without crashing. We'll still be working on resolving this bug, but for now users can use this work around. (special thanks to Suckageawea for discovering this)
