"Lol, good luck with that noob to pro guide OP. I mean, Garry's Mod is all about sandbox creativity, so I don't think 5 easy steps will really cut it. More like, 5 steps to get you lost in the depths of Source engine mods"
"Lol @ mastering Garry's Mod in 5 easy steps, that's a tall order. I've been playing for years and still find new ways to get creative with the source engine. Got any tips for a noob like me, OP?"
Not sure about 5 easy steps, but if you're looking to level up in GMod, I'd say start by learning mapmaking and scripting. Those skills will give you a solid foundation and allow you to create your own custom content. Don't be afraid to experiment and try new things!
