Graphics:
The graphics are somewhat better than the PS2. For the PS3 would clearly have been possible much more.
Gameplay:
Run around, massacre, dialogue for listening, running around, massacre - in between there are small group tasks, where it counts, to press the keys to pre wrote Ender time.
Conclusion:
Here, as so often tried to make the movie with a makeshift cobbled together game more money. The money you can save.
