Steam Officially Makes 3 Games 100% Free until ~October 12

Steam's Free Weekend selection is giving PC gamers a handful of games to check out this weekend, including a highly-rated open-world survival-crafting co-op game in Core Keeper this weekend. It's worth noting that this Free Weekend promotion is a little more scattered than usual, as typically games expire on the following Monday at 10 am PT/1 pm ET (October 12 this time around). While that's true for one of the Free Weekend games, specific expiration date/times are listed below because they are a little disparate.
