I was told certain promos can stack . For instance , I got the two free lines last weekend . One of them I also stacked a Sync Up Drive for free and the other I ' m getting one of these devices for free . In my discussions with reps they were saying this would be fine . I guess I ' ll find out here soon . <| sep |> THIS ! This is why some players seem to never run out of special ammo . These are the smart ones who save their super to get that extra special box or stop the other team from getting it . Special ammo itself isn ' t the problem , ti ' s the players who can ' twon ' t grab boxes . I ' ve seen players on my team running past boxes without stopping to pop it . Like why wouldn ' t you ? Even if you have full ammo it helps your team and stops the other team from getting it .
