As you may be aware we have changed both the prices in the store and the prop menu. The store prices make some wearable items harder to obtain and therefore more exclusive. If you have already bought them, then they are yours. Otherwise you will have to earn more credits to obtain them now. The prop menu prices reflect the fact that too many boxes are available each round or that people flood a cade with them which can lag the server. More importantly, it's supposed to be a challenge to defend yourself from the zombies. Hence these changes have been made. Finally we have changed the ratio so that a $1 donation gets you a 1000 credits. Our hope is these new changes will keep the game interesting for all and a challenge to those who have played the game a long time.
