We mean that literally.
There are big rocks in this Ace Combat: Infinity TGS trailer. Asteroids abound! The event is calle Ulysses Disaster, and it sees the Earth ravaged by interstellar chunks of space rock. Then gameplay footage happens, planes get blown up, a massive flying fortress appears, and we drown in a puddle of ecstasy.
Namco Bandai are bringing Ace Combat: Infinity, which will be a free-to-play title, to PS3 later this year.
