This is an excellent action adventure game for the PSP, offering a unique blend of gameplay and stellar multiplayer. It is open-ended to the point that it may be played nigh infinitely. Its only downfall is the steep learning curve and difficulty, especially when played solo.
Pros
* + Great multiplayer!
* + Immersive gameplay and crafting system
* + Unique mix of 3rd person action/shooter and FPS elements
Cons
* - Gameplay suffers if only played solo
* - Steep learning curve and frustrating difficulty level
