OH GOD I LOVE THIS GAME.
Yeah, it's old but so what?
Anyways:
The player is free to roam the game's open world, not having to focus on the game's storyline.
Progress in the game is measured with Chaos, which is earned by completing missions, destroying government property, collecting items for the factions and reaching 100% completion in settlements and military bases. Chaos unlocks new agency missions and stronghold takeovers. Chaos and stronghold takeovers expand the factions' area of influence, which unlocks faction missions and race challenges. Agency missions progress the story, while faction missions are completely optional. Helping one faction does not prevent the player from helping the others.
The artificial intelligence uses a planning system which enables enemies to perform various actions. Enemies can use the environment to their advantage, taking cover behind objects and adapting to the objects around them. Additional elements include vertical gameplay and a manual aiming system.
There is also a real-time deformation system and individual components can come loose from vehicles.
Initially, the player must acquire weapons and vehicles in the field. Early in the game, the player encounters a black market supplier, from whom weapons and vehicles can be purchased, with an option to have them delivered to the player's location via helicopter. As more Chaos is gained, additional weapons, vehicles, and the extraction option become available on the black market. All weapons and vehicles on the black market have parameters that can be upgraded in several steps, by building upgrades with weapon and vehicle components. There are over 2,000 parts that the player can acquire.
Notable features of Just Cause 2 include the grappling hook, which gives players the ability to tether objects to each other. There are no limitations to what can be tethered. For example, in a high speed vehicle chase, the player can use the grappling hook to attach a pursuing vehicle to the ground, forcing it to stop and causing damage to the vehicle.
In addition, the player has a parachute which is always ready to be deployed, even if it has been deployed and discarded only moments before. This can be combined with the grappling hook and used as a fast method of transport.
The PlayStation 3 version of the game allows the user to capture video of their gameplay and either export it to the XMB or upload it to YouTube from within the game.
TL;DR = GTA on a huge island with deserts, mountains, and forests. It also has fighter jets, commercial jets, attack helis, APCs, etc. There's also an option to capture video and upload it to youtube on the PS3 version.
Sadly there's no multiplayer, but it's still very fun. The graphics are amazing, too.
