You're an average player, playing a below average GMod map. That is, until things quickly go off the rails, and your less-than-stellar horror experience splits off and becomes a wild journey with a literal band of mysterious world-hopping cats! Welcome to Jazztronauts: You're part of the crew now.
In Jazztronauts, you and your friends wield some of the most powerful playthings in Garry's Mod and use them to strip randomly selected Steam Workshop maps of their props and brushes! Barrels, walls, Doctor Kleiner--your Prop Snatcher can take them all! Everything you steal can be turned in when returning to the Hub for cash, which can then be spent at the bar for brand new tools and further upgrades to your existing kit.
While you're in the Hub, now's a good time to mention that those bandmates weren't just for the intro--they're your employers now, and it's up to you to complete menial tasks for them in exchange for bonus cash and new pieces of story!
While cat slice-of-life and cash are good incentives, your real main goal here is collecting Shards! You've been hired to collect exactly 100 of these bad boys--they'll be randomly sprinkled along whatever map you play on. Make sure to collect all of them before you leave a map! (Tip: The bigger the map, the more Shards can spawn! Roleplay maps are your best bet for big Shard runs!)
So, what are you waiting for? Welcome to fetch quest hell: get your friends together, grab those Prop Snatchers, and get stealing!
