Essentially, if the code was paid for by SOMEBODY (ie app redeem sites, EA, who can afford giving away a bajillion codes), it can be reviewed. It acts as if the app was gifted. Then again, if a dev gifts their own app they are only spending the 30% Apple fee.
Ok, its a pretty good game for a first start. I like these kind of top down shooters. Has a feel of a little bit of Revolt to it. I'm definitely going back to it.
