So if you've read the review on Jumper: Griffin's Story, you might think it's bad. Well, it's much worse than that. It's definitely the worst game on Xbox 360. You collect experience to... unlock achievements. You gather collectibles in a loot room. When you go to said loot room, you cannot interact with said collectibles and they are so poorly drawn that they are unrecognizable. The characters you fight look so much like you that you often lose where you are in the crush. In a game about teleporting all over the place you are barred by invisible walls from the majority of visible places. If you quit the game and come back, none of your checkpoints will have saved and you will have to start the chapter over again. This only matters on the last chapter, which is larger than the rest of the game combined. Oh, and did I mention the graphics would be embarrassing on a PS1? (other than drop zone cut scenes).
I suppose it could be worse- Brash entertainment could still be in business despite making terrible games.
But on the plus side, you can get about 400 gamerscore points in 10 minutes! It hands out 50 point achievements for each of the 5 main attacks, 2 more for pulling off combos and another for using a drop zone, all 8 of these come during the 'tutorial' level.
