It was never really free at BB--while the coupons made it seem so, BB caught on real fast and updated their policy quickly. If anyone got it free at BB, count yourself lucky--you were the exception to the rule.
For the rest of us, this is really cheap at Walmart and BB right now. I think someone else had it crazy cheap right now too, but I don't remember who.
Some BB's have been clearancing out the lone gun for a couple of months, so u might find an extra blaster for $5.
The game is a decent rail shooter, with secret rooms unlocked using the red plastic filter found on the new model gun. U can really use any gun, and any red plastic filter to play. All the guns are upgradable in game, which is really cool.
Its good fun for the non-zombie tastes/age groups.
