The Steam mission editor is included in the Mac version.
Monaco: What's Yours Is Mine, the indie heist game from Pocketwatch Games, has made the jump to Mac via Steam. Included in the package - hand delivered by a devious little monkey - is the Steam mission editor, for those who like to play at being a criminal mastermind. "Man, it's nice to have mac and editor launch out of the way so I can drink lots of beer and randomly buff characters," says the mouth of Pocketwatch, MonacoIsMine.
The base game is $14.99, or $44.99 for the four-pack. If you haven't already had a shot at this cheerful little steal-em-up, a précis: you play as one of four shady types, trying to break out of Monaco with a grand series of heists. The maps are filled with guards, traps and other nuisances trying to ruin your day, so you'll need to employ caution as well as your characters' special skills to work your way through without getting nabbed. It can be played either solo or co-op, hence the four-pack; the idea is to have one game for yourself, and pass on three copies to friends.
So, mon ami, have you love in your heart for the life of crime? If so, talk to the monkey; he knows what to do.
