Garry Newman's crazy physics sandbox for the Source engine, the one that lets you manipulate, animate and torture characters from Half-Life, Counter-Strike and Team Fortress, has joined the list of Mac games on Steam.
"What's Garry's Mod?," you might be asking yourself, dear Mac owner. It's the playground with which hilarious and spectacular videos like Half-Life: Full Life Consequences, 100 Ways To Kill Yourself in Garry's Mod and epic Rube Goldberg machines are created. It's not a game; it's a tool. And, like most new Steam releases, it's cheap. Just $4.99 USD.
Newman admits the release has its share of bugs, warning and pleading that we should "please treat this as a beta release." So, buy accordingly or sit it out until Garry's Mod for Mac matures.
Also note that you're going to need at least one of these Source games to use Garry's Mod.
