Exit gives you a change of pace from usual puzzle games and offers a great amount of content.
The reason I say survivors is due to the fact that the stages, which each contain 10 levels, will be set in a burning building, a flooded mall or some other disaster stricken place. These levels will consist of multiple floors and start & finish points with various obsticles in between. As the heroic character Mr. Esc you run a sort of rescue business, its your job to rescue whoever your cliental wishes, this varies from you average citizens to gangsters and all kinds of other people.
The obsticles that you encounter will vary from ladders and ropes to boxes and lifts to fire and water. Each obsticle has to be delt with in a certain way, this could involve simple going around it somehow or by using an item to get rid of the threat. This is just a small example of how Exit mixes up each level to change the experience throughout.
Possible the most important factor in Exit are the types of survivors that you will encounter. These come in the forms of Adults, Young Adults, Children and the injured. Every type of companion, as they are called by the game, have different abilities. The abilities will be in the jumps they can clear, the heights they can climb and fall, the amount they weigh and how much wieght they can push and the gaps they can fit through. The abilities of these chracters will determine what types of people you need and where in the level you will need them. You therefore will find yourself thinking of how to get to one person before another. These characters do have the annoying habbits of shouting phrases over and over again, this has to be the second most annoying thing in this game.
The most annoying thing being the AI of these characters. It is nothing short of dreadful. The companions will not understand how to get from where they are to their destination. They will attempt to simple go from A to B without understanding that they may have to climb some stairs first or use a lift, something which they are incapable of doing. It can sometimes feel as if you are babysitting these companions despite them supposedly helping you.
Exit offers 100 levels in the game itself, but you are given the option to download and extra 110 onto your PSP. This means that you can double the content that is included in the game. All of this will last you anywhere between 10-20 hours depending on how logically minded you are. The levels towards the end can get very difficult and some levels even become more platform orientated which just doesn't work well with Exits game mechanics.
Exit offers a good PSP experience but is too slow and repetitive to really show what a PSP game can do. If you are a very puzzle minded person this is definitely a break from the Tetris and lumines games that you may be used to on your handheld. This may not appeal to the wider audience however, so I would advise that this game falls under the "rent it first" catagory.
