In case you need another reason to purchase Top Gun on iPhone besides our glowing praise, we've got the nugget that's going to put you over the edge: Easter eggs. For example, by inputting the right codenames, you'll be able to transform your fighter jet into a starship or the car from Days of Thunder.
More importantly though, you'll be able to play volleyball over Goose's grave with the disembodied heads of Maverick and Iceman. No, really. If there's ever been a better way to blow two bucks, we haven't heard of it.
