The biggest gameplay innovation is the grappling hook (a.k.a. hookshot), which, when paired with your always available parachute, allows you to get around quickly as well as scale buildings and walls. Hooking onto a car from long distance, and then hijacking it, is cool; it's even cooler when you hook onto a helicopter and throw its pilot out. I found myself muttering, "Get out," more than once.
Then there are the mechanics that just feel broken. Early on, you unlock the ability to call your black market contact. I was told to equip my beacon and then press Y to make the call, but every time I tried this I got an error reticule. With no help other than the vague "tip" to make sure that I was calling in a drop at a suitable location (there was no indication as to what that meant), I finally realized that I had to aim the beacon at the ground and that I had to press Y exactly once in less than two seconds after equipping the beacon. Once you finally get the black market open, you can only purchase one item at a time. What if I wanted to spend all my dough and buy all of the weapons I could? Well, then I had to make a lot of calls.
The save system felt just as awkward. Just Cause 2 let's you save anywhere and at any time, but that's misleading because, when you load those games, you are always taken to the closest stronghold or mission start. I only discovered this from the long drive in the mission I mentioned before, I thought I could create a save point closer to the objective to save myself some driving. No dice, loading that save game put me back at the start of the mission.
This actually ruined the feeling of exploration that could really make Just Cause 2 great. Driving around the island is a lot of fun, and there are lots of collectibles and mini objectives to complete which are not tied to a mission. But if you die while, say, attempting to take out a pesky colonel at a military base you discovered after driving on the other side of the island, you then respawn back at the nearest stronghold. Want to get revenge on the colonel that killed you? I hope you put gas in the tank.
It's worth mentioning that you can "extract" via the black market to any point on the map that you've discovered, but my problems with calling them didn't really encourage me to take advantage of that mechanic.
There are morsels of fun to be had in Just Cause 2. It's a noble attempt at delivering a truly open world where you are rewarded for doing pretty much anything you want to do and blowing up stuff. Using timed explosives to blow up a gas tank while Rico coldly walks away, and then getting a big flashing display of how many chaos points that earned you, is a satisfying feeling. It's just that the moments where everything works like it should are scarce.
Bottom Line: An experiment in sandbox mechanics that rewards you for what you end up doing anyway: blowing stuff up and killing cops. But not all of the systems are refined enough for a AAA game.
Recommendation: Buy if you love causing chaos in huge open worlds, otherwise rent it for some cheap thrills over a weekend.
Greg Tito would like to apologize to all of the innocent citizens of Panau for jumping onto their cars and tossing them out.
