I spent countless hours in Just Cause 3 and it’s subsequent DLCs doing little more than wingsuiting around, blowing up bridges and messing with the physics engine. The fun of Just Cause has always been hurling vehicles around, tethering items together, and attaching rocket thrusters to things that have no business having rocket thrusters attached. If the number of times I found myself ugly-laughing as the newly-redesigned Apex engine worked its magic in my recent hands-on demo was any indication, I’m probably going to end up dumping countless more hours into Just Cause 4.
