Jak II opens up a few years after the original game. After a mishap with a Precursor jump gate, Jak and Daxter find themselves transported to another world. Jak is immediately arrested, for reasons unknown to him, while Daxter is able to escape. The game then jumps two years into the future where we discover that Jak has been the subject of numerous experiments. After escaping, Jak sets out on one mission -- to kill the Baron (the guy who subjected him to the experiments). This immediately sets that all-important 'Mature' tone for the game. As I said before, this isn't anything too extreme, but it's definitely a drastic change from the original. Most of the content comes in the form of language and innuendo (i.e., the Oracle's interpreter is a monkey/parrot named Pecker). The story is pretty adult in the sense that it's not some whimsical 'we need to save the world', it's more of 'I'm going to kill the baron.' Anyone expecting 'Mature' in the sense of
GTA 3 won't find that here as it's more of a PG-13 type stuff rather than R.
After completing the initial 'training' level, you're thrown out into a city. Like the worlds in GTA3 and the first Jak and Daxter, the play area is massive. This world serves as a hub area for the rest of the game, and plays in a style similar to Grand Theft Auto. While you're out in the world, Krimson Guards are walking all over the place trying to find you. For the most part, you blend in with the crowded city streets, but you're not completely safe. You have to make sure you don't attack anyone or steal anything in from of them, otherwise they gang up and chase you. You can steal any of the Zoomers that are in the city in order to travel faster. Similar to GTA, you also follow icons on the map that show you destinations. After talking to the people, you travel to the actual levels of the game. These areas are also giant. They start off small, but as you progress through the game and visit them multiple times, new paths open. These areas are pure platforming. The missions presented in these levels are pretty cool. Most have you rescuing people (or backing people up), but I also did one where I had to find turrets all over the power plant and shoot out 'metal eggs' that were sucking the power out of the core. There are also hoverboard areas, which either come in the form of giant skate parks or 'makeshift' skate areas in the levels -- which make the levels even bigger.
There are also a bunch of mini-games. Most are delivery and checkpoint missions that unlock over the course of the game, but they soon expand to cover things like a skate park and a shooting range. You can also collect Precursor Orbs that unlock secrets.
To be honest, the deeper I got into the game, the more disappointed I became with it. The game starts off with the fundamentals of the original -- big worlds to platform around. But it soon becomes less and less what the original was and more and more a hybrid of a bunch of other games. There are WAY too many GTA style checkpoint, delivery or escort missions. I'm also become increasingly aggravated with the Tony Hawk 'skater' levels; such as the one where Jak has 2 minutes to throw 6 bombs into reactors. The thing is you have to hit the quarter pipe just right and jump at the right time so Jak will throw the bomb in. This is frustrating beyond belief.
This isn't what Jak and Daxter was about. It wasn't about checkpoint missions, deliveries or all the other assorted crap you have to do to extend the gameplay. Jak II is at its best during the platform missions (which are brilliant, in my opinion) and at its worse when it tries to be other games. I wanted to play Jak and Daxter II, not 'Jak Hawk's Grand Theft Pro Skater II.' It's cool that Naughty Dog tried something different, but I really think they left some of the first game's audience behind with the 'enhancements.'
