Valve just recently moved Steam Workshop out of beta, and we're already seeing a ton of great mods ready for your clicking.
We've had access to mods before, that's nothing new. But Valve's Steam Workshop completely streamlines the process of adding them in, making the ability to have smarter AI, new weapons and newly skinned enemies an easier process than ever before. And databased, too!
So what's out there now, roughly four days after its official release? Here are a few that caught my eye.
There are a ton of other maps, skins for the four playable characters, skins for enemies, heck, skins for the defibrillator and ammo packs. There are weapons, from melee and assault rifles to machine guns and grenades. There are menu tweaks and UI changes. New soundtracks and sound effects. Just a metric crapton of things you probably don't need but, hey, you can download now.
