while the bronze booster pack is cheaper than promotions of bronze characters themselves. if you intend on catching up to other players. you should save them for a discounted gold pack or even a challenge pack. if anything, completing 2 stages (prefarably the first 2) of the challenge will award you a FREE bronze booster pack. also try to complete as much of battle mode as much as possible to obtain more credits. if you want, you can also use bronze characters in survivor mode to give you really good gear and augmentations. just dont risk continuing if all 5 characters including 2 substitutes are knocked out.
