Vector Cell (developer) and Lexis Numerique (publisher) have released new footage of Amy, showing how combat in the game works. Since Amy and Lana are just regular people, in most situations, you’ll want to avoid combat by hiding. You can either hide together or separately.
If you must fight, Lana can hit enemies with sticks and other weapons you find lying around. Each weapon has its own durability and will break after being used a certain amount. If you’ve got Amy close by, however, you can use her special powers to help in combat as well.
The other option, which was revealed earlier is to let Lana’s infection mutate her into a zombie. This lets you mingle with enemies, but if you remain in this state for too long, she dies.
Amy is slated for release early next year on the PlayStation Network.
