What it is geareed towards is a lot of entertaining gameplay. And if you're at all a fan of the series, or if you've been looking for something to do with your Guncon now that you've played through Time Crisis
too many times to count, then Point Blank 3
will definitely appeal to you.
The game is structured as a series of mini-games. In the standard game, you go through sixteen of them, randomly picked from over eighty available ones. Once you pick a difficulty level, most of the stages are that difficulty, but there's often an 'Insane' minigame thrown in to make you waste a life or two as you play.
The various minigames range far and wide in variety. There are ones that reward fast shooting (blow up the satellite before it hits the ground), ones that reward accuracy (one bullet to hit a plate at the end of a stick), and ones that reward some sort of weird mix between brainpower and reflexes. Those are generally my favourite. There's one that has you hitting the objects in numerical order--1, 2, 3--and they pop up crazy fast. My all-time Point Blank 3 favourite, however, is the letter-shooting contest, where you have to 'shoot out' as many letters as possible on a grid of 'pixels'. Very cool.
But that's basically the entire game. There are a number of different modes to keep the game going for you and your friends; you can participate in tournaments where it sets up the pairings for you, and you can do Endurance mode when you're alone to see just how long you can last through a long series of games. There's also a training mode that lets you pick any of the minigames and any difficulty level and lets you see just how well you do.
There are a few improvements in the game from the rest of the series--for one, I didn't come across a two-player unfair 'one-shot,' where there's only one thing on the screen to shoot and both players are expected to do it. I always thought that was a cheap way to make a player lose a life in the original Point Blank. But most non-hardcore veterans won't notice anything different other than the changes in the minigames themselves.
