Not out of the box — but the JC2-MP mod makes it co-op and PvP. Just Cause 2 is a classic & campaign shooter game released in 2010, 91% positive on Steam (50,739 reviews), with 90 playing right now. $14.99 on Steam.
Free standalone on Steam (Just Cause 2: Multiplayer Mod); needs the base game. Steam lists Just Cause 2 as single-player, so it won't show up in Steam's own "games we both own" view as something you can play together — Ready Up counts it anyway, marked "Via mod", and you can hide mod-only games with one filter if that's not your thing.
Dive into an adrenaline-fuelled free-roaming adventure with 400 square miles of rugged terrain and hundreds of weapons and vehicles.
