Today progression exists primarily in roleplay and survival servers. However, a sense of progression once existed to a limited extent through a currency system that was implemented during the beta testing stage. It should be noted that JC2 multiplayer sacrifices Just Cause 2's sense of progression and features an "everything is unlocked from the beginning" type of gameplay experience on many servers. The vast majority of servers feature the classic freeroam script, which very basic by itself, though things like vehicle/player spawns can be added to the server's scripts folder to make the freeroam experience feel more like the one featured in the testing stage of development. This leads to the creation of scripts by server owners who are able to put these objects to use. However, objects from the game's files including vehicles, character models, weapons, effects, and dynamic audio can be spawned in to the game world at will. The mod removes the base game's artificial intelligence and story elements, leaving only the island itself.

While JC2 multiplayer is technically a mod, it's less of a modification and more of a face-lift of the entire game.
