Best free addons?

depending on the gamemode you play mate. A tipp: Just search for collections other server owners made and pick the best ones out^^

Ben's dumpsters is really good for some quality dumpster diving!

M9k weapon addons are the shit they are so good the animations are fantastic and the sweps are clean

Star Wars Vehicles are one of the best addons, well made and climatic.
