Build Defense drops you into a nightly siege where zombies, spiders, and other threats close in on your base while you scramble to reinforce walls and set up turrets. Codes hand out free building blocks, coins, and combat items like the God Apple and Toxic Venom Firework, giving you a head start before the waves get rough.
