What is Z Tools?
Z Tools is a free community companion site for Last Z: Survival Shooter, the popular mobile zombie survival strategy game by Florere Game. We provide interactive tools and comprehensive guides to help alliance players maximise their progress.
The site is built for Server 277 players, so all strategies and event timings reflect that server's current season. However, the tools — especially the Alliance Duel Calendar and Research Trees — are useful for players on any server.
