Zombie Squad Defense (좀비 분대 디펜스)

A first-person 3D tower-defense shooter: protect your base crystal from zombie waves as a 4-hero squad - solo with 3 AI teammates, or online with up to 4 friends via a room code. Shoot and slash, build and upgrade turrets, buy 6 guns and 7 skins in the shop, and collect 13 per-gun skins and 9 knives (including a 1% Mythic tier).
